How about opening your own machining shop in Jiaxing, Zhejiang? Mainly making molds. Wire cutting. Lathe.

I suggest not doing it. At present, there are too many people in this industry, the profits are very thin, and the wages of workers are very high, so it is difficult to recruit people. Why not do something else? Go and see for yourself and ask the old-timers in this field. After driving in Beijing for five years, it is hard to say that making money is better than working. It's hard, thankless.
