How is the treatment of Guigang Huangpu River Garment Factory?

It depends on what you do. I once had a friend who worked as a merchandiser there for five and a half days a week. Accommodation (company subsidy+self-paid), free car transfer to and from work, salary 1600 yuan or so. If it is in the production line, the salary is piecework, and you can probably get about 2000.
