There seems to be no swimming training class, but it's good to go to Xiasha University to swim, and there are people to teach. For example, the swimming pool of the Polytechnic University is very good. For indoor, tickets are purchased once in 20 yuan, and they are stuck outside in 200 yuan. Students in the school 150 yuan. Just ask a student to help you with it. You can swim 30 times in normal times and 15 times on holidays (students will go to 5 yuan once during the day and 10 yuan at night). One time during the holiday is 10 yuan)
