Why is the house by the river tilted?

The reason why the roof of the riverside house tilts is as follows:

Rainwater is led to the gutter through the slope, which makes the roof difficult to accumulate water and leak. Especially in the south, there is a lot of precipitation in the rainy season, and it is by the river. If the roof is flat, too much rain will accumulate in the rainstorm, and the consequences of poor drainage will be very serious. Therefore, it is necessary to tilt the cover.

A house is a house for people to live in. Hakka people are called homeowners, Cantonese people are called housing enterprises, and Fujian people are called Cuo. Feng Shui, a folk belief, is different from a dead and buried house, because there are strangers living there.
