There is a two-story multi-functional building in the school, with a supermarket on the first floor and a cake shop on the second floor.
It's very delicious and exquisite, so you don't have to worry.
In addition, if you go out from the north gate of Zhuhai campus, there will be many cake shops. You can also go there to buy cakes.
If the poster is still not satisfied, you can go out from the east gate of Zhuhai campus and take bus No. 10, No. 3, No. 69, etc. to the city center. That would be too much.
