Can you help me provide a better swimming place in Lanzhou?

The best one in Lanzhou should be the Locomotive Swimming Pool, which is located in Jinlun Square. The environment should be the best in Lanzhou, and the price is more favorable than Lanhai, but it may be closed in winter. If that doesn't work, go to Lanhai. Tianlong may have stopped, too The training fee is about 36 yuan. I'm talking about the training fee for professional teachers. Non-professional ones may be cheaper. The best swimming coaches I know in Lanzhou teach in both Locomotive and Lanhai. After asking, I will know

BY the way. Lanhai and Erre are open all year round. The swimming pool in a star-rated hotel is sunny, so I can't afford it, hehe. However, I heard that Lanhai will be closed for maintenance for one month in January. In addition, my very good swimming coach's surname is Zhou, and his telephone number is 1389336898. You can contact him and ask him anything about swimming.
