The word "Zi" is often the explanation and supplement of "Ming", also called "Biao Zi". Qu Yuan said in Li Sao: "The name is right and the word is clever"; "Constant" means "flat" and "spiritual average" means "original". His names "Ping", "Yuan", "Ming" and "Zi" have a meaningful connection. The relationship between "name" and "character" of the ancients has the same meaning, such as: Zhang Heng, who invented the seismograph in the Eastern Han Dynasty, and Mi Fei, a writer who beat drums and cursed Cao, were all upright, and the "balance" in their names and characters was "ping"; The word "Shaoyou" written by Qin Guan in Song Dynasty and the word "Wu" written by Lu You are synonymous in terms of names and words. Another example is Chu Suiliang, a calligrapher in the Tang Dynasty, and Ceng Gong, a writer in the Song Dynasty. Its name and the words "good", "good", "public" and "solid" in the text are also synonymous.
