★New rules for naming children. Both parents’ surnames can be used together

For the first time, the "Name Registration Regulations (First Draft)" has made regulations on naming citizens. Mandatory rule: Citizens should take their father's or mother's surname, but they are allowed to adopt the surnames of both parents. When children adopt the surnames of both parents, they can be named according to the double surnames, but it does not count as a compound surname. Based on the current 1,601 surnames in my country, this approach will add 1.28 million double surnames, thus alleviating the problem of duplication of names in the population with common surnames.

From the actual situation in our country, children are allowed to take their father's or mother's surname, and it is advocated to adopt the surnames of both parents. This can not only show the family and blood relationship between the children and both parents, but also solve the problem of duplication of names in the population with common surnames. The problem also has a positive meaning.

★There are restrictions on the names and words used

Necessary restrictions should be placed on the names and words used by citizens under certain conditions. The "Regulations" stipulate that names must not contain the following content: 1. It is not conducive to the dignity of the country or the nation; 2. It is not conducive to the good national customs; 3. It is likely to cause adverse reactions or misunderstandings from the public.

Taking into account that the number of characters used in Chinese names is usually two to three Chinese characters for single surnames, and three to four Chinese characters for compound surnames or the surnames of both parents, the "Regulations" stipulates: Except for the use of ethnic characters or writing , except for translated Chinese characters, the name should be no less than two Chinese characters and no more than six Chinese characters. For example, if the husband's surname is Zheng and the wife's surname is Fu, they can name their child "Zheng Fu Beckham".

The "Regulations" stipulate that names shall not use or contain the following words, letters, numbers, and symbols: 1. Simplified traditional Chinese characters; 2. Eliminated variant characters, except for variant characters in surnames; 3. Self-made characters; 4. Foreign characters; 5. Chinese pinyin letters; 6. Arabic numerals; 7. Symbols; 8. Other characters that are beyond the scope of standardized Chinese characters and ethnic minority characters.
