Confucius’ Apology - Seeing is Needing.
It says: When one of Confucius’ students was cooking porridge, he found that something dirty had fallen into the pot. He quickly picked it up with a spoon. When he was about to pour it away, he suddenly thought that porridge and rice were hard-earned, so he ate it. Confucius happened to walk into the kitchen and thought he was stealing food, so he taught him a lesson. The student in charge of cooking suddenly realized it. Confucius apologized with emotion and said: What I saw with my own eyes is not accurate, let alone what I heard from hearsay.
