From a legal perspective and in principle, as long as it does not violate laws and regulations, the public security department cannot reject a citizen's name change application for any reason. Some regions have restricted names from using two characters to three-character names.
The "Regulations" stipulate that when children adopt the surnames of both parents, they can be named according to both surnames, which will not be counted as compound surnames. Once implemented, many parents may plan to change their children's names, and the "Name Registration Regulations" (Preliminary Draft)" also stipulates that in order to prevent the abuse of name rights and frequent name changes, after the implementation of the regulations, Chinese citizens who are over 18 years old may apply for name change registration only once.
