I have the tower crane certificate from the Quality Supervision Bureau, but the people who work at work are the certificate issued by the Shanghai Urban and Rural Construction and Transportation Commission.
Can I still use my certificate of the Quality Supervision Bureau? Only so many points, please tell me quickly, very anxious!
What is the tower crane in Inner Mongolia?
I have done it over there, tell the situation, what are the problems?
