I used to have a big mobile phone repair shop on the first floor of the Haixing Smart Plaza in Xihuamen. They hired engineers from Guangdong. But the relative cost is also higher. The shop floor is very formal, and every engineer's desk items are clean and tidy. This is what kind of mobile phone repair shop I saw on the forum before. It can be seen from the most basic cleanliness of the desktop and the neatness of the placement of tools. It's the passage in the middle of the west side downstairs. It was a bit messy and I don’t remember it very well. You can just go and have a look. The cost depends on what problems they detect with the machine to determine the final repair cost
