The categories of "Ben" and "Yong" appeared earlier. In The Analects of Confucius, there are discussions about "the foundation of ceremony" and "the use of ceremony". "Fang Lin asked this gift. Confucius said: What a big problem! Ceremony, not luxury, is quite frugal; It's easier to mourn than to grieve. "Confucius said: the purpose of ceremony is harmony."
