How about East China Branch of China Construction Third Division One Company?

In addition to Guiyang, Guiyang Branch of China Construction Third Bureau has several provinces and cities under its jurisdiction. For the whole China Construction Third Bureau, all levels of Guiyang Branch (production and operation ability, welfare treatment) are in the middle reaches. It is still a relatively strong team in Guiyang market.

This is a branch office, not a project manager's office.
