Xidan Huawei has four floors. There are three sellers of electronic products in the corner. The largest is the Genese cabin. His family buys goods quickly and has a lot of things. A star next to me has a lot of signatures, all of which are not for sale. The store is not small, but I'm not familiar with it. Then there is one in the corner. Then there is one on the basement of Tianzuo Mall near Beijing Institute of Technology.
