who was 1985 season champions but did not compete in 1986 league season due to participate in Asian Club Championship, the tournament was named as National Football League Division 1 Group A, shortly as Chinese Jia-A League, the other 8 clubs of Division 1 and top 4 clubs from Division 2 participated in Chinese Jia-B League. The two groups merged in the 1988 season but divided again in 1989. In 1994, as part of the sports system reform project, the Chinese Jia-A League became the country's first professional football league. The Jia-A league achieved success in its early years, but in the late ’90s heavy criticism existed towards the League's management practices like the lack of continuity in key policies, and some of its member clubs was criticised for a lack of sustainable development. At the same time, the league was affected by gambling, match-fixing and corruption. the chaotic state of Jia-A causes troubled investment environment with sponsors and club owners bowing out. The Chinese Football Association then decided to reform the League system, which ultimately led to the creation of the Chinese Super League. The initial conception is to introduce truly commercial methods and let the professional football market operate more freely, drawing on the experience of professional Leagues in Europe to redesign the league structure and strengthen professionalism. On January 13, 2001, Yan Shiduo, vice-president of the Chinese Football Association, discussed setting up a new professional league system. In 2002, the CFA made a decision to establish the Chinese Super League, which started in 2004. Foundation Compared to the Jia-A, the CSL is a lot more demanding on teams. The CFA and CSL committee imposed a range of minimum criteria to ensure professional management and administration, financial probity, and a youth development program at every club. The CSL published first edition of CSL club criteria in 2002 and revised it several times, club license system was introduced since 2004. Besides the regular professional league, the CSL also has a reserve league, and Youth super league plays in U-19,U-17,U-15,U-14 and U-13 levels. The CSL and China League One's goals are to promote high-quality and high-level competition, introduce advanced managerial concepts to the market, enforce the delivery of minimum standards of professionalism, encourage an influx of higher-quality foreign coaches and players, and gradually establish the European system for player registrations and transfers.
