Why didn't Medert Optics do anything?

Not reliable.

1 maidete optical company is a "three-five" enterprise that has not been certified by the relevant national institutions. Corporate credit is not good.

2, the personnel are very unreliable, the personnel technology is backward, the working hours are long, and overtime pay is not given. The salary is only two or three thousand, and I am still very tired. It's very unreliable, and no one will do it over time.
