How far is it from Xining to Nangqian County? How high is Nangqian?

It is about 1,000 kilometers from Xining to Nangxi’an. The shuttle bus from Xining Bus Station at 16:30 in the afternoon will arrive at about 10:30 the next morning. During this period, we will stop in Yushu at around 8 a.m. the next morning to have breakfast, which takes about half an hour. \x0d\ \x0d\I've sat there once before, at this time, and I guess it won't change much now. \x0d\ \x0d\ Xiangda Town, where the Nangqian County Government is located, is about 3,800 meters above sea level. However, the highest altitude along the way from Xining to Nangqian is over 4,000 meters. I forgot whether it reached 4,500 meters.
