When is admission to Wuzhen free?

Lunch at a restaurant near the entrance of Xizha (Wuzhen Chuanjiacai, highly recommended). After eating, enter the scenic area and wander around without a plan; every corner is very comfortable, and most importantly, very clean. I really love the big fat koi; I could watch them all day. Taking portraits during sunset in the evening looks great. The dining options within the scenic area are reliable; each store has its own characteristics, and there are many customers. After eating, go to Andufang Pier to take a boat to Wenchang Pavilion Pier. There are many lively bars near Tongji Bridge. Finally, walk towards the East Gate exit to fully enjoy the night view of Wuzhen. The scenic area management is quite good; there are no stalls selling stinky tofu or grilled squid.
