Hard construction man, tell me about it.

Most of them come from all parts of the motherland.

At the time of family reunion, they have begun to pack simple luggage, leave their hometown and come to the construction site with the entrustment of their parents and the expectations of their wives and children.

I look up occasionally. On the scaffolding tens of meters high, their figures seemed to fly in mid-air, and I could only vaguely see colorful safety helmets dancing.

It is they who are working hard.
