Since Xinjiang has many neighboring countries which have great Muslim population, it was under threat of terrorism. Thus checking points and police forces are more serious to all people even foreign travelers. In order to ensure the safety of all people and the stability of society, everyone must cooperate with them.
Please do not bring your swill Army knife, pocket knives or scissors with you if you travel by train in Xinjiang. Due to security regulations it is not allowed to bring or express delivery.

We are used to be asked about the safety concerned about Xinjiang. It is true that there were some safety problems 10 years ago, but everything is perfect now in the area. We promise you Xinjiang must be the most safe destination in China. At the same time, we do have causal security check.
