What kind of trees are planted in the yard for good feng shui?

Ancient geomantic omen in China advocated planting flowers and plants widely in the courtyard, believing that they had four functions: hiding water, sheltering from the wind, accompanying germination, dispelling evil spirits, and increasing wealth and auspiciousness. For example, "Ten Books of Yangzhai" holds that "people don't live in barren land" and "the whole house" says: the place to live should be lush vegetation, pine, cypress and bamboo, and there are forests around the house. In particular, Yang Zhai Hui Xin Ji also devoted a chapter to the theory of tree planting.

First, tree species selection

Planting trees in the yard is dispensable. According to geomantic omen, plants can be divided into two categories: bad luck and bad luck. There are two criteria for dividing the perpetrators: one is based on whether there is poisonous gas or venom, which has certain scientific basis. For example, some scholars believe that cordate telosma will emit a large number of particles that strongly stimulate the sense of smell at night, which has adverse effects on patients with heart disease and hypertension. The flowers of oleander are poisonous, and the fragrance of flowers makes people sleepy and reduces human function. Tulip flowers have soil alkali, which is easy to fall off when exposed to hair too much. This is a fierce tree and should not be planted in the yard. The other is the shape of the tree, such as "the tree is strange, and its name is ruined by anger", "the tree is hunched over, and its wealth is exhausted", "the tree is like an ox, and it is ill" and so on. All ugly, dignified and abnormally developed trees are fierce. I'm afraid this is a psychological effect or a traditional humanistic aesthetic concept at work. As for auspicious tree, it is determined according to plant characteristics, meanings and even homophones, and people tend to hold this view in real life. For example, Feng Shui scholars believe that 65,438+03 plants such as palm, citrus, bamboo, Toona sinensis, Sophora japonica, Ganoderma lucidum, plum, Ficus microcarpa, jujube, pomegranate, grape and begonia are auspicious plants, while peach, willow, wormwood, ginkgo and cypress are auspicious plants.

Second, about planting orientation

Ancient geomantic classics have some conclusions about this: "Peach trees are planted in the east, plum dates are planted in the south, elm trees are planted in the west, and plum trees are planted in the north", "Willows are unlucky in front of the door", "Sophora japonica is in the middle of the door, and there are ghosts behind the house", and "There are bamboo forests and trees around the house to make money". From the above conclusions, combined with modern scientific knowledge, we think that some conclusions contain natural science knowledge, while others are one. For example, peach trees are planted in the east because the sunrise is the first in the east, willow trees germinate earlier, and peach blossoms are one of the earliest flowering plants in spring, so it is more reasonable to plant them in the east, elm trees are wet plants, and it is more appropriate to plant them in the west when the sun is not afraid. As for the saying that locust trees attract wealth and elm trees exorcise ghosts, there are probably many superstitious elements. Willow should not be planted in front of the main gate, which may refer to willow "easy virtue", which is psychologically unacceptable.

Third, about the number of trees planted.

Feng Shui advocates reasonable close planting. It thinks: when the surroundings are large and narrow, don't plant many kinds of trees, otherwise it will help to shade them; Only the sparse left and right behind are densely planted to block their emptiness. We agree with this view, but some of the following statements are too superstitious and can be discarded: "A single tree is the door, but a widowed mother and an orphaned grandson", "The door is in the forest, and the sudden illness is more fierce", "Two trees in front of the door hurt more people", "The left tree is not right, and the luck is not so fierce", "The left tree is three to five, and the husband and wife are fighting each other", and "Two trees are sandwiched between houses, and the loss is certain.

Fourth, about the size of the tree.

It is more suitable to plant big trees in the yard, and different feng shui schools have different requirements. In geomantic omen, the formal school thinks it is appropriate to plant rows of big trees around the house to stop the suffocation. In order to meet the needs of the situation, when building a house on the plain or in a wide place around it, trees and flowers can be used to create a pattern of "left green dragon, left white tiger, former suzaku and back Xuanwu", that is, planting big trees at the back of the house, medium trees on the left and right sides, and low shrubs or grass in front. This way is understandable from the aesthetic point of view, which meets people's psychological needs of finding a "land of feng shui", so we can participate in the design. In geomantic theory, it is believed that trees should be planted in high places and low plants should be planted in low places. For example, the theory of "Year of Eight Houses" holds that trees should be planted only when there are natural medicines in the house, and there is longevity and vitality. Dwarf trees or grass can be planted in other directions. Kong Xuan's law stipulates that only God can plant trees, but the direction of zero God is not suitable. This method may have no scientific basis or aesthetic feeling, and should not be used as a reference unless the owner has special requirements.

Verb (abbreviation of verb) on tree type selection

Generally speaking, Feng Shui theory advocates a square garden, which is symmetrical and balanced. Therefore, the overall requirements for plant cultivation can be summarized as: healthy and disease-free, dignified and peculiar, which we can see from the following Feng Shui conclusion. Strange trees are swollen, and evil spirits are imps; bamboo and wood are hung upside down by the water, and children fall into the water; dead trees are used as doors, and people are killed by fire; branches and vines are entangled, and hanging beams are overturned; branches are damaged, and feet are sick; branches are left, and phlegm-fire causes miscellaneous diseases; and roots under trees are swollen, deaf and blind, and sick. It is certain that dead trees, dead trees and diseased trees are not suitable for planting. As for the ugly trees, they should be split in two. Some trees are beautiful because of bending, and they are good because of bending, so we can't exclude them all. Of course, we won't grow those ugly and twisted ones.

Six, about the choice of plant color

Classical Feng Shui books rarely discuss the color of plants directly, but only a few words, such as "the right tree is red, a seductive family" and "the right tree is white, and the children and grandchildren are scattered". I am afraid that the right tree is related to "Peach Blossom" and should not be located on the right side of the pond, otherwise it will be obscene. "White flowers on the right tree" is related to the custom of mourning the dead with white flowers, so it is judged that children and grandchildren will be separated. We think this judgment is nonsense, otherwise the flawless Magnolia grandiflora planted in front of the house would be all wet? Although ancient geomantic theory didn't talk much about what color plants were planted, it believed that everything in the world was composed of five material elements: gold, wood, water, fire and earth, and different colors represented different elements.

Gold-white, apricot and gold

Wood cyan, green

Water-black and blue

Fire-red and purple

Soil-yellow, brown

As for the orientation and the color, Feng Shui has produced a series of complicated theories based on the principle that the five elements coexist and resist each other, so we won't discuss it because of the limited space. According to people's psychological habits of color, some new modern Feng Shui scholars put forward some new views. They think red represents prosperity and enthusiasm; Green represents peace; Yellow represents wealth; Black represents solemnity; White represents cleanliness and solemnity. The author thinks that the above division has certain significance, because it conforms to the psychological set of modern people, and we can refer to it in landscape design.

For various reasons, modern people pay more and more attention to the traditional geomantic theory, and the requirements of landscape engineering for geomantic omen are becoming more and more obvious. Therefore, the study of ancient and modern geomantic theory is beneficial to landscape workers. The author's discussion above is mainly based on the arguments of some ancient and modern geomantic scholars, and some are the inferences of geomantic knowledge. Whether it is right or wrong remains to be criticized and corrected by experts.

Symbols of good or bad luck of feng shui plants

In geomantic omen, different plants are given different meanings. Before choosing plants, we should first understand the good and bad luck and symbolic significance of each plant.

Generally speaking, there are two criteria for dividing plants into good and bad:

One is whether there is poisonous gas or venom.

For example, cordate telosma will emit a large number of particles that stimulate the sense of smell at night, which will have adverse effects on patients with heart disease and hypertension. This plant is considered fierce.

The second is to talk about bad luck according to the shape of the tree. Any tree that is not upright, dignified and abnormal in development is a fierce tree. I'm afraid this is a psychological effect or a traditional humanistic aesthetic concept at work.

Auspicious tree is usually determined according to plant characteristics, meanings and even homophones, which is universally acknowledged.

Plants regarded as auspicious

Oranges: "Oranges" and "auspicious" are homophonic, and potted oranges are good home furnishings.

Reineckea carnea: It is green and easy to grow all year round. It symbolizes "good luck" and is also called Cao Rui.

Toona sinensis: Toona sinensis is easy to grow and has a long life. In some places, children touch Toona sinensis and pray for its rapid growth.

Sophora japonica: It is considered to represent "Lu" and is planted in the courtyard.

Peach tree: According to legend, it is the essence of the five elements, which can control ghosts and ward off evil spirits, and is often hung on the door with peach symbols.

Willow: Like peach trees, wicker is often inserted in the portal to ward off evil spirits.

Gourd: In Feng Shui, gourds are used to ward off evil spirits. Current tests have proved that the "treasure gourd" shaped container can shield the interference of waves and radiation.

Plants considered unlucky

Eucalyptus: Eucalyptus is called the "giant" in the tree. It has been growing for a long time. It is said that the tree died, so the old man had to be invited to plant it. But at the same time, through scientific research, eucalyptus can repel mosquitoes.

Plants regarded as auspicious

Orange, "orange" and "auspicious" are homophonic, and potted orange has become the decoration of people's families during the Spring Festival.

Reineckea carnea is small, green all year round, easy to grow in mud and water, symbolizing "good luck", also known as Cao Rui.

Toona sinensis is easy to grow and has a long life. The custom of touching Toona sinensis is prevalent in some places. On New Year's Eve, children should touch the Chinese Toona tree and turn around several times, praying to grow up quickly. In some places, on the morning of the first day of the first month, children read "Toona sinensis, Toona sinensis, you are king, you grow thick, I grow long".

Sophora japonica is considered as "Lu". The ancient imperial court planted three pagodas and nine thorns, and officials and doctors sat under them, facing the three pagodas, so that the world could plant pagodas in the courtyard.

Ganoderma lucidum has been regarded as an auspicious omen since ancient times. In auspicious pictures, Ganoderma lucidum is often held in the mouth of deer or crane as a birthday present.

The five petals of plum blossom are considered as five auspicious gods, so there is a picture of "Mei Kai Five Blessingg".

Plants considered to have the function of suppressing evil spirits.

Peach trees are said to be the essence of the five elements, which can create hundreds of ghosts, so there is a symbol of peach hanging on the door during the Chinese New Year.

Like peach trees, willow trees put wickers on their doorways to ward off evil spirits.

Pupu, the pu of wormwood leaves in Dragon Boat Festival, is hung by the door, or made of wormwood leaves into a "Ai Hu", which can play a role in expelling poison and evil spirits.

Because ginkgo trees bloom at night, people can't see them, and it is said that there are ghosts, so the artist's seal should be ginkgo wood carving;

The cypress is tall and straight, which is regarded as the length of a hundred trees. It can disperse energy and drive away evil spirits. There are many kinds of cypress trees beside the grave.

"Cornus officinalis" is often a stranger in a foreign land, and he misses his relatives twice every holiday. "I learned from a distance that there was one person missing from the dogwood where my brother climbed. Why does Wang Wei want to "insert dogwood everywhere" in this poem? It turns out that in Feng Shui, Cornus officinalis is a kind of mascot, which can be worn when climbing on the Double Ninth Festival to avoid disasters.

Sapindus mukoraiensis is especially respected. This deciduous tree has white flowers in May and June, slightly larger than loquat, green and ripe yellow, with stones inside and strong stems like plants. The common name is Ghost Seeing Sorrow, and Buddhism calls it Bodhi, which is used to string rosaries, so it is "harmless".

Hulu, why does Zhang use "Bao Hulu" to pack wine? It turns out that in Feng Shui, gourd is considered as a kind of plant that can ward off evil spirits, and the ancients often planted it in front of and behind the house. Modern physical experiments have proved that the gourd-shaped container can shield all kinds of interference from waves and radiation. Zhang used "Bao Hulu" to pour wine, which can not only exorcise evil spirits, but also preserve the taste of wine.

Plants considered unlucky

Eucalyptus, the "giant" among trees that can grow to 20 stories high, is afraid to be lost to young and middle-aged people. It is said that all adults will die. You have to hire an old man to plant this tree. Anyway, when the tree is big, the life span of the tree planter is almost the same.

Fengshui tree

In the south, some villages will keep a small piece of green trees nearby, mostly evergreen trees such as camphor, pine, cypress and Phoebe bournei. As tourists, never touch them. Because this is a Feng Shui tree, also known as Shuikou Tree, although it is only a small piece of lush forest, it is related to the Feng Shui lifeline of the village. The local people are afraid of destroying the Feng Shui of the village and dare not touch every grass and tree there.

Be the laurel tree in front of the door.

Trees must be planted around people's homes, thinking that the four gods have enough space. According to the cloud, there is running water in the east of the home, so it is advisable to plant nine willows in On Behalf Oflong. White tiger has a road to the west. If there is no road, plant seven catalpa trees instead of white tigers. There is a sweat pool for Suzaku in the south (front). If there is no mud pond, plant nine osmanthus trees instead of Suzaku. There is a mountain in the north (behind) that is basaltic. If there were no hills, as for the three trees, Xuanwu would not be needed. In doing so, I thought that the four gods corresponded. People in official positions are well prepared and live a long life without illness.

Except Qinglong, Baihu, Suzaku and Xuanwu, no matter where Uncle He is, he will follow his wishes. But as the ancients said, flowers are planted in the east and red leaves are planted in the west. If there is a pool, pine trees and willows should be planted on the island; Next to the fishing hall, it is best to plant trees such as maple, which can enjoy the cool in summer.

Sophora japonica should be planted by the door. The man who planted a tree near the door of the minister's house is called Huaimen, who is an official of the minister Huairou and the emperor. There is a reason to plant willows in front of the door. But according to the cloud, the door willow must have been planted in front of people or dignitaries. Although this is not customized, it is very inappropriate to plant willow if it is not a family.

A tree can't be planted in the middle of the house, nor can it be planted in the middle, otherwise it will be "sleepy" to plant it on a tree.

Trees and plants are inherently feminine, and there are yin and yang between plants. Generally speaking, green broad-leaved plants belong to Yang, and slender twining plants belong to Yin.

If a house is surrounded by fine vines, then the yin of this house must be particularly heavy.

Some houses have only one wall covered with fine vines, which is also a darkroom house.

To tell the truth, there are quite a few such houses, especially in the suburbs or mountainous areas. If you encounter this kind of house, you should carefully consider whether your luck and energy are enough. Otherwise, if you live in a secluded house for a long time, it will be as fast as two months, and as slow as one year, your magnetic field will be disturbed into Yin wins Yang. At that time, your fortune and health will be inexplicably hindered.

If you really like living in such a "seemingly romantic" house, don't live alone, find more roommates, and use the yang of many people to balance the yin of the whole house.

However, an old house was occupied by vines, and even the windows were covered with vines. It's best not to live in it, anyway, because basically that kind of house is like this, that is to say, the magnetic field of the house itself has been completely magnetized by vulva energy because of its age. No matter how many people you live in at this time, it's useless!

Recently, people began to pay attention to Feng Shui, which is the product of our country's history and has some reasons. Here is an article about Feng Shui. I know more about plants in Forestry College. This is an article about plants. . . The green space next to the house is generally only for the use of residents in this building. In urban planning and design, it is not listed as public green space. However, this kind of green space is the most convenient for residents, accounting for the largest proportion (about 50%) in all kinds of green space in residential areas. Therefore, it is a green space that cannot be ignored. The plants on the green space next to the house have the closest relationship with people. It is necessary to deepen the research and understanding of the relationship between plants and people from the perspective of biology and geomantic omen, and make reasonable arrangements and scientific applications.

1. Plants are spiritual. Between plants, between plants and people, there is often a kind of field-biological field. Plants have "blood type", and there is a certain genetic relationship between plants (consistent with families, genera and species in plant taxonomy). The relationship between distant relatives and close relatives is different in hybridization and grafting. Scientific measurement proves that plants have language, emotions, joys and sorrows. When it breaks its branches, it will release angry waves; When playing music and watering, it will make pleasant waves. Tiantai Mountain and Nanhua Temple have a kind of Lagerot Oemia. When people touch it, its branches and leaves will swing, and it is called "ticklish tree". Mimosa is a plant. As long as people touch it, it will close its leaves quickly. “Mimise SP。” In Luoding, Guangdong, when the wind blows, its leaflets will keep dancing. Empirical statistics show that Clivia in an unharmonious family doesn't like flowering. When the family celebration is coming, Clivia blooms ahead of schedule. After testing 25 different plants, Baxter of the United States proposed that plants have the function of "extra sensory perception". It has brought explosive enlightenment to the scientific community. Experiments show that plants have "memory", induction and superhuman ability to cope with the environment. The oak tree will explode when the lumberjack arrives, and the carrot will tremble when it sees the rabbit growing in the field. Palmate agave is tested by galvanometer, which can reflect the psychological feelings of the tester. Even tracking their owners' daily safety and anger (proposed by Peter tompkins and Christopher Bird in Special Functions of Plants).

Plants can predict information, not only some plants can predict natural disasters (earthquakes, droughts and floods), but also some plants can predict social disasters. In War of Resistance against Japanese Aggression and China, during the national crisis, a large number of bamboos bloomed (white flowers withered). In the late 1980s, in the spring before the flood in Jianghuai, local bamboos also blossomed. The local folk proverb "Bamboo blossoms bring floods home" predicts the floods in summer and autumn.

Plants have aura. Everyone who practices Qigong knows that when gas is often collected from trees, it is generally not collected from small trees. When you gather gas around the tree, you will see that the tree is tired and its leaves are drooping.

2. Plants have yin and yang. Plants have yin and yang properties. Plants that like sunlight, if planted (placed) in a humid environment, will be weak, will not bloom, will not bear fruit or die. Such as: Prynne, Rose, Jasmine, Plum Blossom, Peony, Peony, Rhododendron, Chrysanthemum, etc. This plant needs 1800 lux of light to develop energy normally. Asparagus, giant bamboo, evergreen, green radish, Penglai pine, Brazilian iron, etc. It can also grow normally under 100 lux illumination. This plant can be kept indoors or in the shade for a long time. It belongs to negative plants.

Flowering and fruiting plants prefer heterosexual co-planting to homosexual block planting or single planting. Solitary yang is not born, and solitary yang is not long. Such as ginkgo trees, planted in the same sex, produce ginkgo. It is common sense for fruit farmers to reduce the yield of single apple. The highly evolved Clivia is called a "gentleman" because it is not popular, and its seed setting in October is like the "pregnancy in October" of human beings. For a time, it was not well cared for, cut off moisture, withered, refined, elegant, and lost its "small popularity." Being regarded as a "gentleman" in plants is the result of high evolution. Its evolution comes from cross pollination. Although flowers are bisexual, there are stamens and pistils on the calyx, and pollen can be given and received by themselves or different plants. However, self-pollinators do not seed (fall off by themselves), and can only seed after pollination by different stamens. Ensure the glory of Clivia from generation to generation. Corn, a grain crop, has alternating lines of yin and yang in pairs, so it has even lines, or 14 lines, 16 lines and 18 lines. There is no growth of odd lines. The yin and yang properties of plants are universal.

3. Plants combine five elements. There is a "field" between plants and everything. Under the action of the field, the particles of each object can influence each other, transfer and change each other. The proverb "bronze does not store gold, and gold is impure" comes from the summary of folk experience. Gold exists in bronzes for a long time, so it is not pure, but bronzes contain gold. Fossils of animals and plants are not caused by temperature and pressure, but by the gas field of rocks. Modern scientific research has gradually uncovered this mystery. 1988 Soviet scientists found that there were particle fields around objects, including human bodies, buildings and plants. The intensity of electric field between plants depends on the conditions of biological constraints. China's concept of five elements can be used to adjust the relationship between life and restraint. Decorating the site with the five elements of plants is not only ornamental, but also functional. It can adjust the environment, adjust feelings and support the body. For example, the garden buildings near the water are equipped with "black" (low brightness) plants to regulate the kidneys of the human body. Such as pine and cypress, peach, lotus, etc. In order to regulate the heart and nerves, red series plants and flowers belonging to the fire in the five elements are planted. Such as fire pomegranate, kapok, ivory red, maple, red mulberry, red iron, red grass, red cinnamon and so on. The plant for regulating lung can be a white series plant belonging to gold in the five elements. That is, plants with white bark and gray or white leaves. Such as Melaleuca, eucalyptus citriodora, murraya, Prynne, Trachelospermum, white water lily, ice water flower, etc. The plant regulating liver can be a green plant belonging to wood in the five elements. Such as green peony, green rose and a lot of green trees. Plants that regulate the spleen and stomach can be yellow plants belonging to the soil in the five elements. Such as Camptotheca grandiflora, Jasminum giraldii, Jingui, Jin Ju, Huang Zhonghua and Yellow Rose. It is common for plants to grow together and resist each other. Agriculture, forestry and horticulture should understand that, for example, grapes planted next to pine trees will not bear fruit, while grapes planted next to elms will bear sour fruit.

And the relationship between plants and people. For example, pregnant women are afraid of cypress trees next to the house, and the smell of trees promotes vomiting. As the saying goes, "the banyan tree can't tolerate people", and the gas field of banyan tree is not good for people. It's not near the house. It is not suitable to sleep under the grape trellis, and the gas field is not conducive to the human body. There is a folk saying that "peach willows are planted in the east and elms are planted in the west; Lizi jujube is planted in the south, and apricot pear is planted in the north. In addition, there is "happiness after the house, ghosts migrate." Plant it in front of the white orchid house and send the fragrance of beautiful flowers. " The pomegranate in the sun is red as fire, and the plum in the shade is sour. "Tao Yuanming, a poet in the Eastern Jin Dynasty, resigned and lived in seclusion. There are countless folk sayings and poems praising him, such as "on the shady back eaves, in front of Luotai", which are suitable and unsuitable for plants and the environment. Word-of-mouth articles summarizing the experience of the relationship between health and grams should be studied and used for reference.

4. Seek formal luck. The shape of trees in the green space next to the house is related to the quality of the house from the perspective of Feng Shui Situation School. Trees can benefit and harm human beings. Avoid evil spirits: ① Don't stand in front of doors and windows. The cosmic energy that nourishes the living environment constantly acts on houses and houses in the form of microwaves. Windows and doors are the main exits. Microwave experiments show that standing wave interference will occur when a tiny needle stands at the mouth of microwave antenna. From this perspective, the traditional concept of Feng Shui is not only empirical and statistical, but also scientific and correct. The conventional saying is that the word "wood" in "door" is called "leisure", which is a simple circulation form induced by Chinese characters. Helps to remember hints. There are also the word "wood" in the "mouth", including the word "sleepy". That is, to avoid the trees in the middle of the yard. "Yin also." The yin of the hospital is set in the center of the hospital, which is yin over yang, so it is taboo. The imperial court is the Tai Chi of Artest, and the heart of the imperial court is the "heavenly heart" of Tai Chi. It is the acupoint of Chongyang and cannot be suppressed for a long time. (2) Street trees and hedges should avoid rushing to houses. Hasty information guidance that may lead to suffocation is not conducive to life. (3) Avoid trees blocking doors and windows. It is not conducive to ventilation and lighting. The shade belongs to the shade. ④ Avoid building huts under big trees. There is a saying that "the home is under a big tree, and disasters often come home" ("Ten Books of Yangzhai"). Being in a cool place all the year round is not conducive to lighting and hygiene, and it is easy to cause thunder and fire. ⑤ Other trees with unlucky images should be avoided in the common sight of doors and windows. Such as strange trees with swollen carbuncle, hollow trees, "neck trees" with vines and crooked trees. These forms of trees have ominous images guided by image spells and argot, so they are not suitable for greening beside houses.

5. Plants should be suitable for folk culture. In the long history, China people have accumulated a lot of sensory impressions on the beauty, ugliness, good and evil habits of the main greening plants, as well as the customs and context handed down from generation to generation. The choice of avoiding and avoiding the good and bad atmosphere of urban and rural residential buildings can not be ignored in the planning and layout.

All previous dynasties in China paid great attention to the geomantic function of trees and flowers. Such as peony in Luoyang, osmanthus in Suzhou and Hangzhou, pomegranate in Chang 'an and willow in Bahe. Chen Tingjing, a famous doctor in the Qing Dynasty (a geomantic master of the imperial court), said in Notes of the Imperial Palace: "The government wants people to be suitable, planting peaches, willows and elms in the east, plums and red dates in the south and apricot flowers in the north." These statements are very reasonable, because they conform to the physiological characteristics of botanical tree species, such as peaches and willows, which like warm sunshine, so they should be planted in the east of the house; Plum trees and jujube trees like to dry and should be planted in the south of the house; The branches and leaves of elm trees can block the sun in the west, so it is best to plant them in the west of the house; But apricot village doesn't like sunshine, so it should be planted in the north of the house.

There is a middle door and a patio between the inner rooms. On the one hand, Sophora japonica can be planted in the patio, on the other hand, it can also play a masking role in the inner room. If evergreen trees are planted behind the house, it can prevent the deep house yard from being exposed to outsiders.

Therefore, one of the major principles of the ancients in the site selection of residential buildings is that no big trees can be planted in front of the main entrance of residential buildings. From today's scientific point of view, the bread here contains a certain scientific truth: because big trees will block the sun, make the room dark and dull, affect the air circulation in the room, and easily lead to lightning strikes. In addition, the shade of big trees is easy to breed mosquitoes and flies, thus affecting the health of indoor owners; Trees can also attract birds to live, and bird droppings can also cause environmental pollution. For another example, elms and locust trees are very old, and the big houses in ancient houses are often in outhouses and ancients. In order to avoid the disaster of "haunted houses", relying on their simple understanding of nature, the goal of building houses is to have an "auspicious house" that can "prosper in five generations". Say it again; "No mulberry before, no willow after, no cypress in the courtyard"; "Blue grass and bamboo help Wenchang, and there are good children at home."
