I have been entangled in the outdoor activities of the baby, and I didn't intend to come to Huaihai Memorial Hall and feel very good. There is no ticket to enter the gate. During the epidemic, many indoor halls were not open, but the outdoor environment was very good. There was a small forest on the right hand side of the south gate. There were many elderly people playing chess and cards. There were more elderly people in this activity. Here you can teach your child something and remember something.
