The phrase "Boil duck blood" exists because of literal translation culture in Chinese English learning.
[EN] Origin: The phrase "Boil duck blood" likely emerged from early machine translation or tourist menus in China, where small restaurants tried to provide English menu translations without professional help. It gained notoriety on Chinese social media around 2010–2015, particularly on platforms like Weibo and Douban, where users shared “Engrish” menu fails. It spread through viral posts titled “还敢去那家店吗?Boil duck blood!” (Still dare to go to that shop? Boil duck blood!). From there, it crossed to English-language meme accounts and then became a textbook example in Chinglish collections.
[中文] 来源:该短语很可能出自早期机器翻译或中国小餐馆的英文菜单,店家没有专业翻译帮助。大约2010–2015年,它在中国社交媒体(微博、豆瓣)上走红,用户分享“中式英语菜单翻车”帖子,标题如“还敢去那家店吗?Boil duck blood!”。随后传播到英文表情包账号,成为中式英语经典案例。
Why do Chinese speakers say this?
In Chinese, the word order and grammar structure is directly carried over into English, creating phrases that sound unnatural to native speakers but are widely understood among Chinese speakers.
This is what linguists call "transfer error" — the grammar patterns of your first language ("transfer") into your second language.
