病从口入，祸从口出(Bìng cóng kǒu rù，huò cóng kǒu chū)Disease enters the mouth, and misfortune comes from the mouth

Explanation

“病从口入，祸从口出”是说病毒常常因饮食不注意而入侵，灾祸往往因说话不谨慎而招致。老人们常用这句话告诫我们要注意饮食卫生和说话艺术，这两个小句也经常可以单用。
“病从口入，祸从口出” means that sickness often enters the body through food and drink, while disaster can come from words used incautiously. Elderly people often use this phrase to remind others simultaneously about food safety and courteous speech, though each half can be said separately as well.
