What is the general work like at Guanlan Yifuwan Electrical Factory, Baoan District, Shenzhen?

Shenzhen Yifuwan Electrical Factory is a Hong Kong-funded enterprise. The boss’s surname is Lin. The products made in the factory are basically exported to Japan or Europe and the United States. My friend worked as a customs broker there, and worked with Pu The salary is about the same, about 4,000 a month, and there is social security. This factory was originally used to process supplied materials, but a few years ago, the factory had a lot less orders and my friend left his job. Later, I heard that the factory was no longer good and Hong Kong had withdrawn its investment. Fortunately, my friend has found a new job. It doesn't matter.
