Why Chinese People Say Brush tooth

[EN] Origin: The phrase "brush tooth" is not from a specific meme or TV show; it is a persistent, organic error that emerged from Chinese English education and product labeling. Timeline: It likely appeared as early as the 1990s when China began mass-producing household goods with English instructions. First observed on toothpaste tubes and hotel bathroom signage. Spread path: Initially seen on local brands’ packaging (e.g., "Brush Tooth Cream"), then shared by English teachers and expats as a humorous example. It later circulated on Chinese social media platforms like Weibo and Douban, and then internationally through Chinglish photo blogs and forums like Reddit (e.g., r/Chinglish). Today it remains a classic example. [中文] 来源：非特定网络梗或电视节目，而是源于中国英语教育和产品标签的长期习惯性错误。时间线：最早可追溯到20世纪90年代，中国日用品开始附带英文说明。首次出现在牙膏管和酒店卫生间的提示牌上，如“Brush Tooth Cream”。传播路径：先由英语教师和在华外籍人士捕捉并分享，随后在微博、豆瓣等中文社交平台被当作搞笑图片传播，再通过Chinglish图片博客和Reddit等国际论坛扩散。至今仍被广泛引用为中式英语经典。
