What are the legal restrictions on building toilets behind rural houses?

As long as it is within the scope of the homestead granted to you collectively, there seems to be no clear legal provisions.

However, due to its particularity, the location of the toilet should be convenient to use, and the space should be used rationally to make the courtyard look harmonious, and the taste should not affect the normal life of oneself and neighbors.

However, there is a saying in China Feng Shui that "Left Qinglong and Right White Tiger" refers to wells and pools, and the white tiger refers to latrines. Most rural houses in China are also built in this format.
