Natural pools in Yantai City

The swimming center in the sports park should be close to Yantai University. It has new facilities, recycled water, and the disinfectant content meets the standard. You can buy cashier's tickets, 30 pieces for 450 yuan, or 400 yuan if you have a coupon. When applying for a card, you will get a free card with a minimum purchase of 1,000 yuan. Each time you are charged 15 yuan, 1,000 yuan will give you 100 yuan, and 3,000 yuan will give you 600 yuan. It is the same as the swimming training center on Southwest River Road.
