Are you looking for customer service or shop repair? In terms of customer service, there is one in North China (the buddy downstairs reminded me, hehe. Just cross the ocean to the east (Xinhua Bookstore). If it is a small shop, there is a Luyuan mobile phone city between New Century and North China, next to the east of China Mobile. On the second floor, there are many mobile phone repair shops, but you should look after the repairs yourself and don't be replaced by them. Besides, the price must be reduced. It's too dark. Anyway, there are mobile phone repair and sales shops in North China New Century Square and this street. But you can cut it, after all, there are many businesses. Customer service, then there is nothing to say, hehe, pay as much as you should, and you can't bargain.
