What is the origin of the 7-day long holiday?

1September, 1999 18, the State Council issued the National Festival and Memorial Day, and decided to increase the number of public legal holidays from 7 days per year to 10 days per year. The three legal holidays of Spring Festival, May Day and November Day, plus two weekends before and after the adjustment, form three long holidays of seven days in a row. During the May Day holiday in 2000, domestic tourism became a craze, so three seven-day long holidays were called "Tourism Golden Week". During the 1999 "Eleventh" holiday, 200 1 Spring Festival and "May Day", the national holiday tourism coordination and command mechanism and information forecasting and statistics system have not been established. During the 200 1 "May Day" holiday, due to insufficient supply and insufficient prediction of the situation, the countermeasures could not keep up, many key scenic spots were overcrowded and dangerous, and tourists in some areas were stranded on the streets. In view of this situation, the State Council issued relevant documents and decided that the National Tourism Administration should take the lead, and set up a national inter-ministerial coordination meeting office in conjunction with the National Development and Reform Commission, the Ministry of Public Security, the Ministry of Construction, the Ministry of Railways, the Ministry of Communications, the Civil Aviation Administration, the Ministry of Commerce, the Ministry of Health, the State Administration of Industry and Commerce, the State Administration of Radio, Film and Television, the Bureau of Statistics, the Bureau of Religious Affairs, the Cultural Relics Bureau and other departments to regularly release tourism information, guide passengers, and coordinate the handling of major traffic, safety accidents and emergency rescue. Accordingly, all provinces, autonomous regions, municipalities directly under the Central Government and key tourist cities have also established provincial and municipal holiday tourism coordination meetings and holiday tourism offices, forming a national, provincial (autonomous regions and municipalities) and key tourist cities three-level holiday tourism coordination mechanism and information forecasting and statistics system, which has been officially put into operation since the "Eleventh" Golden Week in 2000. Through the practice of eight golden weeks, a strong and long-term working mechanism for organizing and coordinating golden weeks has been formed nationwide, and the goal of "safety, order, quality and efficiency" has been achieved.
