Fengcheng to Dandong is 40 kilometers, and Dandong to Dalian is 260, less than 300 kilometers! It is strongly recommended not to run at high speed. Your fucking round trip is 200 yuan, and a few oil books are enough, unless you are Audi Q7, Porsche Cayenne, Volkswagen Tucson, Cadillac Commander ... Forget it, the underground tunnel from Dandong to Fengcheng is very general, but the one from Dandong to Dalian is very good! The scenery is very leisurely all the way.
