Excuse me, where do I get off at Zhengzhou Xintian Outlets Metro Line 6?

Get off at Century Building Station and change.

Subway is a kind of fast, large-capacity and electric traction rail transit built in cities.

Trains run on fully enclosed lines, the lines located in the central city are basically located in underground tunnels, and the lines outside the central city are generally located on viaducts or on the ground.
