The couple born in the 1990s planned to go to Chengdu from Anshan, Liaoning, take 318 after a day's rest, plan to finish 318 in 10 days, and then drive back to Anshan after staying in Lhasa for two or three days. How many days will it take? The car is a 1.2T Corolla, so it should work. Only the boy drove alone, and he didn't want to rush too much, for fear that his body would not be able to bear it. How long will the whole route take? I don't know how long it will take to go back to Anshan from Lhasa. How much is the general cost of accommodation and meals?
