Hot springs are separate for men and women, and men and women can't be together.
The bathing industry belongs to the special line, especially the relatively high-end bathing center, and the hot spring bathing also belongs to the special line. Men and women are not allowed to be together in hot springs or other bathing centers.
Bathing industry has a strict management system, which should be strictly observed and cannot be destroyed. If found, administrative punishment will be given and other responsibilities will be seriously investigated.
