One bathroom is enough, why should China have two

Generally, 2-3 bedroom buildings often live in 2-3 generations, each with its own bathroom, which can take a bath, wash clothes, and be "convenient" without interfering with each other. One is not enough, there will be a scramble in the morning or before bed, it is definitely not enough!

I don't know about this yet... It's simple. It is the principle of order of the young and the old. Plus there are some regulations. Wake up early may not be able to use the right... Just look at Japanese TV dramas.

The squatting you said should be raised so that the same floor can be padded, otherwise it is ugly to see the convex bottom of a stool trough downstairs. As for entering the door on a big step, this is no longer the case in the current building, because the floor slab is poured, and the bathroom is partially lowered, which will only go down a little bit to prevent water from flowing out of the bathroom. The steps in the handwashing area may be for children, and adults do not need them, and now there are also special lower basins for children, so there is no such practice in raising the handwashing area. >>>More

In this way, it is not easy for others to see from the bottom, which is a respect for other people's privacy. >>>More

The flue of the toilet is used for ventilation and odor exhaust.
