The Chinese characters of the word "Jiao" explain that "Jiao" means "full-time teaching for teachers", emphasizing professionalism and professionalism, which is derived from the original meaning of "filial piety". "Filial piety" originally means that children completely give up farmland and farming to escape to full-time study in order to take care of the critically ill elderly all day, thus having the meaning of "full vocational education for teachers" and further developing the meaning of "respecting teachers and being parents". The word "teaching" comes from the cloud and meat, and "meat" refers to "human body"; The original meaning of "cloud" is "rotational aggregation", for example, the fog scattered in the sky is assimilated into a part of a large cloud through the process of rotational aggregation and escapes as "assimilation", so "education" refers to the assimilation of people who already exist in the world (that is, "meat"), that is, instilling mainstream social values into minors, so that they can smoothly enter the mainstream society and grow into people who are useful to society; For barbarians, "a gang of one" means that a civilized person and a barbarian help each other in pairs, prompting them to give up backward ideas and customs, respect and accept advanced Chinese civilization ideas and customs, and become a member of the Chinese civilization circle (please refer to the original meaning of the word "benevolence"). In short, "teaching" means that teachers give them lessons wholeheartedly, and "teaching" means assimilating minors and barbarians and making them qualified members of China civilized society.
