Beijing Guoan Football Club is one of the most storied and supported teams in Chinese football, based in the capital city and competing in the Chinese Super League (CSL). Their home is the iconic Workers' Stadium, a cauldron of noise and passion. The club was founded in 1992 and is owned by the CITIC Group, a state-owned conglomerate; their distinctive green home kit has earned them the nickname "The Green Lions." Beijing Guoan was a founding member of the professional Chinese Jia-A League and has always been a central figure in the sport's development in China. The club's most successful period came in 2009 when they won their first CSL title under manager Hong Yuanshuo, led by stars like Xu Yunlong and Darko Matić. In the modern era, Guoan remains a perennial contender, consistently finishing in the AFC Champions League spots with a squad featuring high-profile foreign imports and Chinese internationals. The fan culture is among the most intense in Asia, with the capital's supporters creating an intimidating atmosphere at the Workers' Stadium. Beijing Guoan is more than a club; it is a symbol of capital pride and a cornerstone of Chinese football.
