Dehao Optoelectronics, Intel, Pfizer, Angang New Rolling-ThyssenKrupp, Volkswagen Engine/Gearbox, Doblin Precision Spinning Machine, etc.
All the above enterprises have open recruitment.
There are also some state-owned enterprises, such as Western Pacific Petrochemical, which are difficult to enter and basically do not see open recruitment.
The website of each company is listed on its official website.
I hope it helps you.
