Road trip cost and time from Zhengzhou to Lhasa

It takes about 8- 10 days for Zhengzhou to take the Qinghai-Tibet Highway to Lhasa, and 1-2w is enough. You must bring a spare tire. We should also prepare some common tools and a gasoline iron drum with 20 liters of oil. The key is the 1000KM highway from Chitai to Dangxiong, which is desolate and high in altitude. (And roadside gas stations often run out of gasoline) You can go to Xining (750KM) first and go up the mountain in Golmud. You don't need to prepare oxygen when you are in good health. But chewing gum is indispensable. I suggest reading the travel notes in QQ37 1505589.
