I haven t taken the subway, so please ask if there is a toilet in the subway

Not on the subway.

Subway stations are generally set up.

Generally, there are stations with a lot of traffic, and there are basically no small stations.

No, you need to get off the bus to go to the convenience, and then get on the bus after the convenience.

Shenzhen Metro has it, every station has it, Guangzhou doesn't have it, and other cities don't know it.

Some of the stops in the middle of the subway have toilets, but there are no toilets in the subway.

There are on both sides of each platform, so don't worry.

There is no subway in the subway station You have to ask the staff, after all, others also need to go to the toilet.

There must be. There is no one in the subway car, there is one in the subway station.

There is no one in the carriage, and there is one in the station.
