At present, in Yueyang City, in order to strengthen the physical exercise of primary and secondary school students, it is free. Students can enter the school free of charge from 2: 30 to 5: 30 noon. Remember, be sure to bring your student ID card or campus card. In short, you must prove that you are a minor. PS: The free swimming pool is open-air. Be sure to prepare for sun protection and wear a hat.
As for Zhong Da swimming pool, it is underground, too dark for swimming. I advise you not to go.
