Places you can visit during the day are Jinli and Kuanzhai Alleys. For fun, you can go to the beautiful scenery in Wenjiang and Happy Valley on Ximen Third Ring Road. For leisurely drinking tea, you can go to Wangjiang Park near Jiuyan Bridge, which is free of charge. The places where entertainment is concentrated at night are Jiuyanqiao Bar Street or Shaoling Road, as well as the entertainment center next to Rainbow Bridge. There should be many snack festivals on May Day in Jinli. However, the food at the Snack Festival can only be eaten as snacks. The place I often go to for dinner is Huayang Riverside Restaurant Street. Cheap and delicious. Of course there are many in the city at South Gate and West Gate, but they are definitely more expensive than those in Huayang. Have fun!
