According to relevant legal provisions, children do not need to have the same surname as their parents.
Legal Analysis
According to relevant laws and regulations, citizens need to go to the relevant departments with relevant documents to change their name. The following conditions must be met for adults to change their name: first, the person must express his/her wish to change the name; second, the reasons must be sufficient; and third, the person must promise to bear all civil and legal liabilities arising from the name change. Those who have been deprived of political rights in accordance with the law and are subject to criminal punishment and reeducation through labor may not change their names. After a citizen changes his or her name in accordance with the law, the original name will be kept as the "former name" for future reference. That is to say, you need to write a name change application to the police station where your household registration is located. After it is stamped, go to the household registration section of the local public security bureau to register. Of course, you must bring your household registration book. It can be officially changed about fifteen or seven working days after submitting the file. Your previous name and current name will be written in the household registration book. When you need to use your diploma or something to prove your identity, you must bring your household registration book with you. When the public security organs formulate administrative regulations, they should not only consider the administrative power of the police, but also consider the consistency of the entire legal system. It is wrong to think that changing a citizen's name may cause trouble and inconvenience to household registration management and the management of citizens' criminal information, thereby restricting citizens from exercising their private right to change their name. After a citizen's name is changed, the public security agency can truthfully record the citizen's former name in various file information. The citizen can deposit, trade in stocks, pay and receive various insurance premiums under the original name. After concluding a contract, the citizen needs to use the new name. To continue to exercise rights and fulfill obligations under your name, you only need to go to the public security organ to issue a certificate of name change. Changing a citizen's name should not have a negative impact on household registration management and public security management.
