What does it mean that autumn is like an autumn chrysanthemum?

You are like a chrysanthemum in autumn. The colder the weather, the more it drives.

Criticism of the poem, this life interpretation of the prosperous old age, his wife and children complacent; Originally, life was happy, but financial resources were like water springs.

I think it means that what I did when I was young was complicated and uncertain. Fortunately, with the support and help of parents, the best thing for your family is money. In other words, you must leave enough money for the rest of your life. Don't squander your wealth, but you will be sad when you are 36 to 40 years old. It is like autumn chrysanthemum, and it is expensive to exhaust all your efforts.

Just like Jin Juhua in autumn, it's expensive to run out of effort, but in the end, it's easy to get pregnant.

Chrysanthemum plants are generally 30- 150cm high, with erect or semi-prostrate stems, quadrangular or cylindrical shapes and colors ranging from green to purple-brown. Oval to lanceolate, 4- 12 cm long and 2- 10 cm wide, pinnate edge, deep or shallow leaves, acute or round base, coarse serrations, green to dark green leaves; The natural flowering period is May-65438+February, with a round pattern, a diameter of 2-20cm and a color of white to deep purple.

Chrysanthemum originated in China, with a long cultivation history, rich varieties and ever-changing colors. It has high ornamental value and is deeply loved by people. The earliest written records of chrysanthemums can be found in the book Zhou Li: "The swan goose is a guest, the sparrow turns into a water clam, and the chrysanthemum blooms yellow flowers (that is, yellow flowers)". The naming of chrysanthemum is explained here.

Since Wei and Jin Dynasties, chrysanthemums have gradually become common. As early as 2,500 years ago, there was a record in the Book of Rites and the Moon Order that the autumn moon was full of yellow flowers. The ancients first knew chrysanthemum from its medicinal and edible value. Chrysanthemum has gradually developed into one of the richest cultivated plants in the world through cultivation, natural hybridization and artificial cultivation.

Kitamura, Japan, believes that modern cultivated chrysanthemums are obtained by natural or cultivated hybridization between wild diploid chrysanthemums in North China and tetraploid chrysanthemums in South China. Professor He Dai made a detailed study on the origin of chrysanthemum, obtained the phylogenetic tree of chrysanthemum resources in China by means of quantitative taxonomy and cluster analysis, and pointed out that modern cultivated chrysanthemums mainly originated from hexaploid chrysanthemums and tetraploid chrysanthemums, and all kinds of wild chrysanthemums also participated in the origin process to varying degrees?

Chrysanthemum originated in China, and its varieties were formed and developed in China. Up to now, China is still the center of genetic diversity of chrysanthemum varieties. However, in the cultivation history of 1600 years, there is no record about the origin and variety formation of chrysanthemum. This left the world with an eternal mystery.

The biggest difference between chrysanthemum and other cultivated plants is that many cultivated plants can find similar species in wild species, but there are huge differences between chrysanthemum and the same wild species, many intermediate links in evolution are missing, and the interspecific succession sequence is obviously interrupted, which is the biggest mystery of this problem so far.
