The blue and green canopies down there are covers for a night market.
The market serve some Indian food at night, as well as other delicacies around the country.
I dont't know why they have the Indian dishes, my aunt told me the dishes are served by several Indian international students who are really good at "飞饼"。
I was watching one of them making the dish last night. The student(chef?) reminded me those Chinese acrobatics, I mean, his performance is really wonderful.
