In addition to the original meaning of "teaching", the word "teaching" also has a style called "teaching", such as the proclamation of ancient princes and princes. The ancients said, "Teaching is effective." "Teaching" also means "imitation" or "learning".
After the orders of the superiors are given, the people have to obey them, so the proclamation can also be called "teaching". For example, in Xiao Tong's Selected Works, there is Zhang Xiu Liang Miaojiao written by Fu Liang for Liu Yu in the Southern Song Dynasty. From "teaching", it can be extended to the meaning of "making", such as Bai Juyi's Pipa: "Qu Ba can teach good before serving." In other words, when the music is finished, musicians can enjoy it very much.
