However, how this association is sustained in everyday practices within China's unique socio‐cultural‐political context remains underexplored. This study examines the raciolinguistic construct of Mubai, a central recruitment criterion in China's ELT industry, and analyses how Mubai codifies the explicit conflation of Whiteness and English nativeness, persistently privileging Whiteness over qualifications through a highly prescriptive recruitment process, which undermines teaching quality, produces unsustainable labor practices, and perpetuates structural racism often unacknowledged in Chinese public discourse. It highlights how Mubai both sustains and destabilizes racialized ideologies of English in China.\n\n摘要\n在英语教学领域，“母语主义”常与 “白人性”密切关联。在中国独特的社会文化政治语境中，此种关联如何在日常实践中得以维系，尚未得到充分关注。本研究以中国英语教育行业的关键招聘标准“母白”为分析对象，从种族语言学视角切入，探讨该概念如何系统性地建构并强化“白人即英语母语者”这一关联。研究发现，通过一套高度规范化的外教招聘机制，“母白”标准持续将种族特征置于教学资质之上。这一机制不仅影响教学质量、助长不可持续的用工模式，而且延续了中国公共话语中常被忽视的结构性种族主义。本文进一步指出，“母白”现象实则同时扮演着双重角色:它既维系又动摇着中国社会对英语的种族化想象。\n"]
