From Luding County, go towards Leshan, and follow the green mountains and green waters all the way! Although the scenery of Line 318 is not bad, the road is too narrow, and there are many construction sites for road construction and bridges along the way. The road conditions are also good and bad, and it is easy to cause traffic jams. Sure enough, it was blocked in the Erlang Mountain area before crossing the tunnel. The convoy couldn't see the tail, and it was very sad that people sat there waiting!
