2. Name of the incident card Source: The jade card first carved by Lu Zigang, a jade sculptor in the late Ming Dynasty. One of the cards, Zhang Yu, took its homonym "no decoration" and named it "no decoration event card". China people believe in Buddhism, and the Buddha said: Nothing is something, so the "nothing card" is regarded as a "wishing card" and an amulet, and everyone is vying for it. "Nothing is nothing, nothing is a good thing" and "more is better than less".
