Not a great name for basically the only black person in the books.
Cho Chang = Both are Chinese or Korean LAST names. ‘Cho’ isn’t a first name in any Asian language, so she’s mixing and matching languages and cultures. She also only describes her as ‘Asian’ in the books, furthering how little effort was put in.
It’s like saying ‘Lombardi Fernandez’ is a European name. Ignorant on multiple accounts.
