There is a person whose surname is "Shen". Can he name his child? Just call it "Shen" with no other words after it. The Public Security Bureau's household registration book and ID card allow it.

No, the so-called name refers to the surname and first name. It is not allowed to have only the former without the latter or only the latter without the former. I can’t find any specific regulations that say this is not allowed, but believe me, you It is impossible to convince the staff of the government agency. There must be two words or more in the household registration book.
