No. A Chinese name places the surname first, followed by the given name. However, in an English-speaking context, people sometimes introduce their names using the 'given name - surname name' format, to avoid confusion of listeners. But in serious official contexts, surname still comes first.
Usually the longer one is the given name, and the shorter one is the surname. In Chinese language, which is a monosyllabic language, each character has exactly one syllable. As a result, the one-syllable surname is usually shorter than the given name, which typically consists of two characters, though it can also be one, with two being more common.
Yes. Every given name was carefully chosen by the parents. Choosing a name is a huge project and sometimes painful. However, the beauty and meaning behind the Chinese characters can be lost in translation. P.S., ask your Chinese friends about the meaning of their names when the time feels right. 😅
