Is the denture factory better in Shenzhen or Beijing?

Shenzhen, of course. First-class enterprises such as Sizhou and Hyundai are all in Shenzhen. Domestic second-rate well-known enterprises, such as Yang Zijing, Kangtaijian, Jiahong, Yamamoto Zhen, Yang Ming, etc. Beijing doesn't even have a third-rate factory. Although there is a branch in Yang Zijing, it is still far from Yang Zijing, let alone first-class.
