Is it ok for users to buy bus tickets in Luntai, Xinjiang?

generally speaking, it is not necessary: if the parties travel by coach, they only need to submit the original ID card (temporary id card) within the validity period, but generally do not need to submit the household registration book (children under the age of 16 need the household registration book when traveling with them).

Provisions of the Law of the People's Republic of China on National Identity Cards:

Article 15 When performing their duties according to law, the people's police may check their identity cards upon showing their law enforcement certificates under any of the following circumstances:

(4) Where it is necessary to find out the identity of the relevant personnel in railway stations, long-distance bus stations, ports, docks, airports or places designated by the municipal people's government that are divided into districts during major events;

(5) Other circumstances where identification is required by law.

in any of the circumstances listed in the preceding paragraph, if the people's police refuse to check the resident identity card, measures shall be taken to deal with it according to the relevant laws and regulations.
