Generation name

Generation name, variously zibei or banci, is one of the characters in a traditional Chinese name, and is so called because each member of a generation (i.e. siblings and cousins of the same generation) share that character, unlike surnames or given names.

Where used, generation names were usually given only to males, although this varies from lineage to lineage and has changed over time.

Generation poem

The sequence of generation is typically prescribed and kept in record by a generation poem (banci lian 班次聯 or paizi ge 派字歌 in Chinese) specific to each lineage. While it may have a mnemonic function, these poems can vary in length from around a dozen characters to hundreds of characters. Each successive character becomes the generation name for successive generations. After the last character of the poem is reached, the poem is usually recycled though occasionally it may be extended.

Generation poems were usually composed by a committee of family elders whenever a new lineage was established through geographical emigration or social elevation. Thus families sharing a common generation poem are considered to also share a common ancestor and have originated from a common geographical location.
