Guanzhong Building and Innovation Building have a large flow of people, and Bainaohui is on a higher floor. If there is a technology market, it would be much better to have your own shop. If you want to open a shop that focuses on computer chassis power supply, I suggest that it is better and more reliable for you to be in the technology market or Guanzhong Building.
