How about Qinhuangdao Sitai Yida Company?

Honestly, I've been there, too So-so. A small workshop, dust removal equipment really dare not compliment. I have seen several companies in Beijing, Tianjin and Baoding, all of which are much better than this. Basically, they just spray water through a big blower. There is basically no technology. You know those qualifications, it is easier for government departments to do this for the development of enterprises. Interpersonal relationships, you can search again. I found it too. After seeing the relationship between men and women and chaotic management, I decided not to go. Look at other companies. Ding Long, whatever.
