China implements nine-year compulsory education, including primary school and junior high school, but excluding the cost of senior high school.

High school is short for high school. Middle schools in China are divided into junior high schools and senior high schools (generally referred to as junior high schools and senior high schools), both of which belong to the category of secondary education. High school is a higher education institution after the end of nine-year compulsory education in junior high school in China. Generally, it is a three-year system, that is, one year of high school, two years of high school and three years of high school.
