What about Shenzhen Guanli New Material Co., Ltd.?
The company produces white separators for lithium batteries, with about 60- 100 employees. This is a company run by Taiwan Province people. The working environment is not so good. There is an irritating toxic smell in the workshop, which is the smell of chemical solvents imported from Japan. Smelling it for a long time makes my head numb. I'm worried that working here for a long time will affect your health. The other is a high-temperature workshop.
