Schools have been established by government departments, businesses, trade unions, academic societies, democratic parties, and other organizations. In 1984 about 70 percent of China's factories and enterprises supported their own part-time classes, which often were referred to as workers' colleges. In Beijing alone, more than ninety adult-education schools with night schools enrolled tens of thousands of students. More than 20,000 of these students graduated annually from evening universities, workers' colleges, television universities, and correspondence schools - more than twice the number graduating from regular colleges and universities. The government spent 200 yuan (¥) to ¥500 per adult education student and at least ¥1,000 per regular university student. In 1984 approximately 1.3 million students enrolled in television, correspondence, and evening universities, about a 30 percent increase over 1983.
