Last name is Hu. Is a nickname okay?

Of course. Names refer to the names of people, things and things, which can be divided into broad and narrow sense, as well as nicknames, aliases, nicknames, birth names and so on. Hu's nickname is disability, which broadly includes the surname and first name of citizens and the names of legal persons and unincorporated organizations. In a narrow sense, it only refers to the surname and first name of citizens and is a combination of names and words. In ancient China, names and characters were used separately, and now they are collectively referred to as "names".
