What about Dongguan Spectrum Standard Experimental Equipment Technology Co., Ltd.?

I've been working on spectral standards. To tell the truth, this company is really not so good. The boss has a bad personality and no integrity. The company has a large turnover of personnel, and the resignation salary is not paid. He asked the boss for a salary. He said that he had quit the spectrum standard. What a big joke! Hehe, this kind of company is really unique! Friends who want to cooperate with them or go to their company should be careful!
