Is the toilet in the train sleeper a toilet

There are two toilets in each carriage.

One sitting, one squatting. >>>More

It's similar to a household toilet, with a button or a handle, just pull it. >>>More

Depending on the vehicle type, the toilets will not be closed when the casual train stops, and all the toilets will be closed when the in-line train stops.

You can wash your face and brush your teeth by train, there is a washbasin, the toilet is not dirty, the toilet is directly open to the outside and underground, so it is generally not too dirty.

I've sat on it, and there is a toilet. The soft sleepers I've sat in have toilets, but they are usually locked and not allowed to be used, and you have to ask the conductor to explain the situation, and he will open it for you.
