What is six masters and seven Obsids?

It seems to have something to do with feng shui ... I only know a little.

Six benevolence is a divination of yin and yang and five elements. On the 10th day of work, Ren represents Yang Shui, and there are six Ren over 60 years old, which are called Six Ren: Ren Shen, Ren Wu, Ren Chen, Ren Yin, Ren Zi and Ren Xu.

Seven Yao refers to the seven shining stars in the sky: the sun (the sun), the moon (the lunar calendar) and gold (Taibai), wood (the old star), water (the morning star), fire (the fluorescent star) and earth (the filled star and the town star).

The eight doors are: Hugh, Shengmen, Injury, Doumen, Jingmen, Death, Surprise and Open.

According to the legend of the nine planets in Feng Shui, there are one white, two black, three green, four green, Huang Wu, six white, seven red, eight white and nine purple.

In the ancient calendar of China, A, B, C, D, E, Ji, G, Xin, Ren and Gui were called "ten heavenly stems", while Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai were called "twelve earthly branches". The ancients used heavenly stems and earthly branches to represent years, months, days and hours. The year, the month and the day are like four pillars supporting the building of "time", so they are called four pillars. Heavenly stems and earthly branches values of year, month, day and hour are called annual column, moon column, solar column and time column respectively.

take for example

On February 25th, 20 10, 2 1 was represented by branches, that is, when the Reform Movement of 1898 was carried out on May 3rd, the year of Gengyin, the first word was heptylpentyl pentyl.

It is the four pillars of heavenly stems, and the second word: Yin is the four pillars of earthly branches. These eight words are the eight characters of this moment.
