Dear God .........., is the medical device market in Zhengzhou good now? What are the better companies? What should I pay attention to in this industry?

I don't know if you mean the dealer or something. This industry is not bad, because China is aging. If it's from Hebei, it's really bad and irresponsible, of course it's cheap. If things are good, Jiangsu Xinsheng, Shanghai Mutual State, Yuyue, Foshan Oriental and Sangui are all very good choices.
