I know this very well. It is a holding subsidiary (group) of SINOMACH China Electric Research Institute (formerly Guangzhou Electric Research Institute) working in Huadu, and now it seems to be preparing for listing. It is a state-owned enterprise. It depends on how to talk about it. It would be a tragedy if you were allowed to live in Huadu (half an hour's drive from downtown Huadu). It is best to take the shuttle bus every day. Abide by the labor law and enjoy the welfare benefits stipulated by the state. The electrical engineer you are applying for should sign a contract with Qingtian directly. If you are applying for ordinary workers or something, you can only sign a contract with a labor dispatch company.
If you go to the excitation, it should be possible. Qingtian excitation is quite famous in the national hydropower industry. If you don't inspire, you will be average. Please ask again if there is anything unclear.
