Chinese education is a Chinese two-language teaching aimed at Chinese children and language culture inheritance education. The Chinese language teaching demonstration board is different from international Chinese education, and has the characteristics of repeated Chinese language teaching and Chinese culture inheritance. The Chinese teenagers are children of overseas Chinese, and generally obtain Chinese language culture fumigates of parents and relatives, and have certain Chinese background. The Chinese education is between the first language and the second language teaching, the teaching characteristic of fusion of culture inheritance and the second language teaching is presented, and a series of high-quality Chinese teaching field teaching resources are accumulated.
