In the old campus, there is a Dragon Night Market near the Second Hospital, with many snacks. It seems that it doesn't open until after 4 pm, and it takes 5 minutes to walk to Huaihai West Road in the city center 10.
If you don't know, you can transfer to the Cultural Palace and get off at the Second Hospital. 1 The bus passes through the city center.
That's all I know. I hope it helps you.
Is this ok?
