There are 30 off-campus personnel/time, and you can apply for a card. 15 trips to 300 yuan, valid for 3 months. There is no limit to the number of people at a time, which means that you don't think you can swim 15 times in three months. You can invite friends or something. Three people go at the same time and cross out three times.
I can swim 10 years. I learned it in junior high school. So I don't think the choice of swimming pool should be too sloppy. The swimming pool of the National People's Congress is an Olympic training venue, so the conditions are good. Because it is the school swimming pool, there is no problem in hygiene. Swimming lanes are divided into deep water area and shallow water area. Only after passing the deep water certificate can you swim in the deep water area.
