Why can Haining build a subway?

Excellent location. Haining enjoys a superior geographical position and can build a subway. Haining is located in the southwest of Jiaxing, close to Hangzhou. Most sections and stations of the Hangzhou-Shanghai intercity railway are within Haining's jurisdiction, making Haining the first county in Zhejiang to open a subway. In subway construction, it is necessary to pay attention to the planning and location of subway lines in the early stage of construction, and comprehensively consider urban development planning, population flow and traffic flow.
