We plan to go in March, and the route is Jiayuguan-Dunhuang-Lanzhou -Xiahe-Labuleng Temple-Baoji-Xi 'an. What precautions are needed, mainly in terms of climate?

Jiayuguan and Dunhuang are relatively dry, so you should pay attention to drinking plenty of water. It is best to carry disposable wet wipes, which can be wiped when it is inconvenient to drink water inside or outside the car. It's still cold in March, and it may snow. Take down jacket. Muslims in Lanzhou should pay more attention to halal food in their lives. Labuleng Temple has a better climate in Gannan, but they still need clothes.
