Origin note
昌 is presented as a transmitted ancient-lineage surname, not merely as the word for brightness or prosperity. The strongest recurring layer connects it with Changyi, a son of Huangdi and Leizu, born in the Ruoshui tradition and later associated with Shushan woman Changpu and their son Zhuanxu/Gaoyang. Later surname sources say branches of that lineage used the ancestor-name character Chang as a surname. Other sources preserve additional layers: a Ren-surname branch descended from Huangdi's sons, and a tradition from a Huangdi-era minister named Changyu. These are kept as parallel surname traditions, while the ordinary character meaning remains a literacy note rather than the origin claim.
