Excuse me, what is the mode of upstairs high-rise building and downstairs shopping mall?

You're confusing me. I looked it up. There is a residence in Beijing Caishikou. As you said, it is a small apartment, and here is the business circle. They call it a serviced apartment.

I don't know if you are talking about serviced apartments.

Example: Chongwenmen, Beijing, with Metro New World Shopping Mall downstairs and Taihua Apartment upstairs.

Guanganmennei Street in Beijing, with Caibai Shopping Mall downstairs and Fuming Apartment upstairs.

Shenzhen-Futian, downstairs is over the rainbow Shopping Mall, upstairs is fashionable apartment.
