Qionglai Yang 'an subway has been built for a long time.

There is no subway plan. Yang 'an in Qionglai City is too remote, and most of them are polluting enterprises. In order to clean the air in Chengdu, furniture enterprises will gradually move away and sit in a worthless ruined city without spending resources, so there is no subway planning. Subway is an independent rail transit system, which is not affected by the ground road conditions and can operate normally according to the designed capacity, so as to transport passengers quickly, safely and comfortably.
