This stems from a folk feng shui formula, "Ming Tang is like the bottom of a pot, and the rich man is hard to compare."
Tang Ming pays attention to complete buckling, loop formation, distinct heights, smooth surroundings, low nest in the middle and flat heights around, just like the bottom of a pot. This is Tang Ming in Kyrgyzstan.
Attached to the original feng shui formula:
The front is like the bottom of a pot, rich and unparalleled; Qinglong transferred the case, the family was rich, the white tiger crossed the hall, and the family was ruined;
Yang Zhai concave, Yin Zhai convex; Yin is not concave, and Yang is not on the top;
Yin Zhai decides life and death, Yang Zhai decides wealth, and the eight characters decide life. The official looks after the ancestral graves, and the wealth looks after the family.
