2. Take one of the parents' surnames apart, that is, name them by family name, and decompose the Chinese characters used by one of the parents' surnames into two characters. Chinese characters in China include two categories: single characters and combined characters, of which combined characters account for the majority, so many Chinese characters can be taken apart, such as the father's surname is Long and the mother's surname is Hu, so when the father's surname is used as the surname, Hu can be used.
3. The homonym of surnames is adopted. Sometimes surnames limit the direction of our naming, and some surnames are simply not suitable for naming. This is a homonym of surnames, just like the name of the second son in Lingzhi Zhang, Chen Long. Someone may ask Chen Long's son how to name Zhang, because the second child takes his mother's surname, and the word "Chen" in the second son's name is the homonym of Chen.
