The division of arts and sciences is an educational system implemented in some countries and regions in the world, such as Chinese mainland, Hongkong and Taiwan Province Province. That is, the teaching course is divided into arts and sciences, and students can choose and then carry out education in different subjects. The division of arts and sciences in Chinese mainland started with 1977 resuming the college entrance examination. But in fact, this system originated from copying the Soviet model. The Soviet Union lost a large number of intellectuals in World War II, and post-war reconstruction urgently needs to train all kinds of professionals through subject education. After Chinese mainland 1949, there was an urgent need for professionals, so the pace of differentiation between arts and sciences began. First, eight earliest foreign language schools, including Xi 'an, Nanjing and Chongqing, were established, and the merger of universities began in the 1950s. At that time, industrialization was the main goal of economic construction. In order to meet the demand for professional talents, similar professional colleges were merged into professional colleges by 1952, and a university system adapted to the planned economic system was established. Such a merger has strengthened the professionalism of engineering colleges, but it has also caused a narrow scope of majors, and the separation of science and engineering, arts and sciences, grammar, finance and economics has also been cut. However, before the end of the Cultural Revolution, there was no division of arts and sciences in senior high schools in Chinese mainland. 1977 after the college entrance examination system was restored, senior high school liberal arts departments began to classify and select talents. The division of subjects is generally carried out in senior one and senior two. Although arts and sciences are divided into disciplines, they all include politics, history, geography, physics, chemistry and biology. Compulsory courses: Chinese, mathematics, foreign languages (English, Russian or Japanese), liberal arts integration: politics, history, geography and science integration: physics, chemistry and biology, but the current system requires liberal arts to retain the teaching of physics, chemistry and biology; Science only keeps political subjects. But at present, this is only a symbolic reservation in many schools, and it is more just to cope with exams or superior inspections. Teachers don't pay much attention to practical teaching, and most students despise these subjects. And if the school directly deletes these subjects from the curriculum after exams or other inspections.
