Not bad, the charge is cheap. I used to hold activities in 688, but now I don't know. By the way, when you go to the gym, if you sign up in it, many coaches will recommend some protein powder and muscle powder to you. Don't buy it, no matter how exaggerated they say, they won't buy it. Too expensive and too fake. It's best to buy it in the market. Also, the coach will let you take private lessons. If you have money, please do it yourself. If you have no money, give it to me.
