Yihe su is the pinyin of one crisp in Chinese, which is an allusion: Saibei sent a box of crisp to. Cao Cao wrote the word "crisp" on the box and put it on the desk. When Yang Xiu saw it, he took a spoon and shared it with others. When Cao Cao asked him why, Yang Xiu replied, "The books on the box are fragile. How dare you disobey the orders of the Prime Minister?"

Modern Chinese means:

When Yang Xiu ate Crispy Three Kingdoms, Cao Cao's main book, Yang Xiu, was very clever. On one occasion, Cao Cao wrote three spaces "crisp" on his favorite pastry box. When Yang Xiu saw this, he opened the box and shared cakes with others. After Cao Cao asked, Yang Xiu said solemnly: "The box says' one person has a crisp bite', and we dare not disobey the wizard's orders and eat separately."

In this way, a fragile combination is given the meaning of sharing, one bite for each person.
