Basic education is a dynamic concept. At present, the de facto basic education in China refers to all forms of education before junior high school (including junior high school). In a narrow sense, it refers to nine-year compulsory education. In a broad sense, it should also include family education and necessary social life knowledge education.

Some people classify high school education as basic education, but this type of education has not been popularized in China at present, so in fact, high school education is not basic education. With the development of China, it is estimated that by 2020, high school education will be basically popularized.

Basic education is the knowledge that people need to master in advance in order to gain more knowledge in their growth. Just like laying the foundation before building a house, if you want to learn a language well, you must start with literacy.
