3:30-8:00 pm every day from Monday to Friday. Open all day on weekends. You can call 1 14 to ask. I often go swimming there. I went there yesterday. There are more people. The water is ok, not too cold. As for water quality, I feel that construction is better than maritime. The management of Dagong swimming pool is also better than that of maritime affairs. By the way, a ticket to 20 yuan is like a sailing student ID card to 7 yuan once.
