I went to the hot spring swimming pool in Gaojialing, and it was hot spring water, which was completely different from the water in Shuidutou. There is a hot spring under that place. I suggest going. Very good. Unlike other places, tap water is tight and it takes a long time to change. Their house changes every day. The pool may not be big, but it is enough for swimming. The important thing is to change the water every day. Don't worry.
