Go in from the west gate of Zhongshan Park on Thursday and Sunday afternoon, go straight and go north, and the river is there. There are many people on Sunday afternoon.
On weekends, I went to Zhongshan Park to watch the tulip exhibition. I didn't expect to see hundreds of people gathered by the Tongzi River at the east gate of the park as soon as I entered the door. The south bank of the whole river is crowded with people.
