Tao Xingzhi's "Little Mister" is an educational organization form put forward by Mr. Tao Xingzhi under the background of vigorously promoting education in China in the 1920s and 1930s. It means "knowledge is communication", that is, everyone teaches others the words he knows and the culture he has learned anytime and anywhere. Under this system, children are the main communicators, and education is popularized through children teaching children and children teaching adults. Mr. Tao Xingzhi advocated and popularized this form of education as an important key to popularize education in poor countries. The appearance of Tao Xingzhi and Mr. Small has played a positive role in promoting the civilian education and rural education reform in China.
