‘Ōuhuà’ (欧化) literally combines ‘Ōu’ (欧), short for ‘Ōuzhōu’ (Europe), and ‘huà’ (化), meaning ‘to transform’ or ‘-ization’. Together, it denotes the process or result of adopting European (and more broadly, Western) customs, values, institutions, language features, or aesthetics. Historically, the term emerged in late Qing and Republican-era China to describe intellectual, educational, and architectural shifts influenced by Western contact.

Today, Ōuhuà is used critically or descriptively in academic, cultural, and journalistic contexts — for instance, discussing Westernized urban planning, loanword-heavy Mandarin usage, or fashion trends modeled on European styles. While often neutral, it can carry a subtle connotation of cultural dilution or uncritical imitation, especially when contrasted with terms like ‘zhōnghuà huà’ (Sinicization). It does not refer to superficial imitation alone but to systemic influence across social domains.
