Where is the best place to learn swimming in Taiyuan? Where is the best swimming personal trainer?

I personally think the swimming pool at the Garden International Sports and Culture Center is better. The water quality of the newly built venue is good, and the temperature is generally around 26 degrees, which is suitable for exercise. I swim there all year round and I feel it is really good. Good, and the coaches there are very professional and nice people. I personally think that especially the female coaches there will be very serious and professional in their guidance.
