Are you tired of doing ordinary work in the tunnel at the subway station?

Tired. The subway construction site is in the tunnel 24 hours a day. In order to make the subway pass faster and sweat like rain, the general work is the most common work, and cleaning and handling are very tiring. Subway is a form of railway traffic, which refers to the urban rail transit system that mainly runs underground, that is, the abbreviation of "underground railway" or "subway".
