The explanation for building a house is this: one column equals ten feet, one meter equals three feet, and one column equals about three meters. One-foot-one-two-floor refers to the columns on the first floor and the second floor, which are one foot high and about three meters and three capitals.
Nine feet nine is three meters three stigma, which means that the stigma on the first floor and the second floor is ten feet. Actually, it's 9' 9 stigma, 3 meters.
The height of the first floor is 10 feet (about 3.6 meters), which means everything is fine. The height of the second floor is 9 feet 9 (about 3 meters 3), which means the height of the roof is 6 feet 6 (about 1 m 1), which means good luck is just around the corner. The inclination angle is about 30 degrees, and the Golden Triangle is stable.
Of course, you can be nine feet nine on one floor and have money forever. This choice is ultimately for the sake of comfortable life, good mood and good luck.
The first floor is 3.6 meters high and the second floor is 3.3 meters high, which is the ultimate height, not just numbers, but a kind of confidence in life. Spacious storey height will greatly enhance the creative space of decoration, enhance the comfort of residence, and extend the activity space and viewing horizon.
