Hai Yin Fitness I applied for an annual card in Hai Yin, which is located at a fork in the road, around today in April. The price is quite good. At that time, it was a 1200 card with many projects and activities and professional services. I feel that Hai Yin is still good, but I have been there for more than a dozen times. I don't have much time. Second, I'm too lazy to go alone. Ah, what a waste.
