Is it necessary to wear a bathrobe or towel ?

In fact, there was no requirement. When entering, you had to go to the bathroom to wash your body clean, then wrap yourself with a bath towel and go out of the bathroom door, find a place to hang the bath towel, and then I would go into the water, get up and wrap myself with the bath towel to go back to the bathroom. The mouth of the pool was about 4-5 meters away from the entrance of the female bathroom, and then indoors, so it was still very convenient.
