My classmate lives in Hedong, and said that there is a good gym in Hedong at dinner the other day. There is billiards, and a coach leads all kinds of events one day (that's good). The equipment is also quite new, and the price is a bit high. It seems that the rose card of 120 is unknown.
Most regular gyms can take a bath, at least until now I have never seen a gym without a bath, hehe.
