I am an amateur swimming coach in Shenzhen. Because my team members are going to have winter training, I am familiar with the swimming pools around Nanshan and Baoan District. I hope my answer can help you. There are many indoor heated swimming pools in Nanshan District, mainly residential areas. Let's talk about a few first: 1, Guishan Villa indoor heated swimming pool, standard 25-meter swimming pool, very beautiful. 2. China Merchants Serene Phase III and Phase II each have an indoor heated swimming pool. 3. The 25m standard pool heated swimming pool in Nord International Garden is also very good. The price is basically around 35 yuan. I feel that the price is a bit high for ordinary consumers. But there is no way. Heating pool water in winter requires a lot of water and electricity costs, and the operator's cost is very high. So it's nice to have a swimming place. 4. The indoor heated swimming pool in CITIC Hongshuwan is on the ground floor, so the air is poor, the light is dark and there are many mosquitoes. Objective evaluation, please don't misunderstand.
