Which factory in Shenzhen has high wages and good treatment?

That depends on which factory works overtime. For example, in the factory peak season, it's almost twelve o'clock in general, and some people can get three or four thousand yuan a month. In the off-season, they just get the basic salary. As far as I know, the overall salary of Peng Hao factory and Huayang Optoelectronics, Meigu and Sanhesheng is acceptable and relatively stable.
