Breakthrough in the construction of north-south subway transportation in Qingdao.

On December 16th, the section of the Qingdao Metro Line 15 project constructed by the China Construction Second Bureau has been completely connected, marking a key breakthrough in the construction of this major transportation artery that connects the north and south of Qingdao. It will help the project progress smoothly.
