In the Spring and Autumn Period, a man in the Song Dynasty got a piece of jade and offered it to Zihan, a high-ranking official. Zihan did not accept it. The person who offered the jade said, "I will give this jade to you." The jade carver saw it and thought it was a precious jade, so I presented it to you." Zihan said, "I regard integrity as my treasure, and you regard it as my treasure. >Jade is a treasure; if you give it to me, we will both lose our precious things. Why don't you keep the jade, and we can each have something we think is precious?" So Song said. The virtuous people of the country said: "It's not that Zihan has no treasures, it's just that the things he treasures are different.
