We are going to Luoyang, Xi, Xinjiang and Dunhuang. What should we take? What's the weather like there?

Generally speaking, it is good to keep warm if you are not acclimatized. The temperature difference between day and night in Dunhuang, Gansu and Xinjiang is relatively large. You should take a thick coat. When you are away from home, you should take care of your luggage and manage your important finances. There is nothing special to pay attention to, just like playing in Zhejiang. One thing is that there are many ethnic minorities who believe in Islam in the northwest. They don't eat pork, go to restaurants marked "halal" and don't order pork.
