with 12 teams in the league. The inaugural season was plagued with controversy, which continued from the former league, Jia-A, and where, since 1999, scandals such as match-fixing and gambling had been uncovered. This resulted in the loss of interest in the domestic game, low attendances and great financial losses. The original plan was to have one relegated team and two promoted teams for the 2004 season and 2005 season, thus increasing the number of teams in 2006 to 14. But the CFA's decisions caused the relegations to be cancelled for these 2 years. For the 2005 season, the league expanded to 14 teams after Wuhan Huanghelou and Zhuhai Zobon won promotion from China League One. The Zhuhai team, formerly named Zhuhai Anping, had been bought by the Shanghai Zobon real estate company and relocated to Shanghai for the 2005 season, and subsequently renamed to Shanghai Zobon. In 2006, the league was planned to expand to 16 teams with the newly promoted Xiamen Blue Lions and Changchun Yatai. However, Sichuan First City withdrew before the start of the season, leaving only 15 teams when the season started on March 11. Shanghai Zobon, after another change of ownership, was renamed Shanghai United. In 2007, the league was again planned to be expanded to 16 teams, but once again it found itself one team short. Shanghai United's owner, Zhu Jun, bought a major share in local rival Shanghai Shenhua and merged the two teams. As a result, Shanghai Shenhua retained its name as it already had a strong fanbase in the city, while Shanghai United pulled out of the league. In 2008, the season started with 16 clubs participating for the first time, however, Wuhan protested against punishments made by the CFA after a match against Beijing Guoan, and announced its immediate withdrawal from the league, which left the season to finish with 15 clubs. Since 2009, the league has run with 16 stable clubs participating each year. Two are relegated to China League One, and two are promoted from China League One each season. In 2010, the CSL was beset by a scandal going right to the top of the CFA. The Chinese government took nationwide action against football gambling, match-fixing and corruption, and former CFA vice presidents Xie Yalong, Nan Yong and Yang Yimin were arrested. On February 22, 2010, CFA relegated Guangzhou Yiyao for match-fixing in 2006 China League
