Zheng Xiong received organised football training in his hometown of Wuhan with their youth team where he was trained as a goalkeeper. By the time he was 17 he was unable to make the transition into professional football after 4 years at Wuhan because his coach believed that he was too short to make it as a goalkeeper at 1.78 m. Deciding to retire he went off to Wuhan Police Vocational College instead to be a police officer, which he became in the late 1980s.
Management career
Zheng returned to football in 1995 when he gained the position of deputy general manager for the Ministry of Public Security of the People's Republic of China financially backed club Qianwei Huandao. In 1998, the club moved to Chongqing and Zheng left them to pursue his dream of becoming a coach when he joined Shanghai Pudong as an assistant coach in 1999. After spending a short time with Shanghai Pudong, he returned to his hometown of Wuhan where he started as an assistant before moving into youth coaching. After gaining a reputation as a rising coach, he joined the Chinesenational team youth setup before he went into his first senior coaching position with third-tier club Hubei CTGU Kangtian, whom he guided to a playoff promotion spot at the end of the 2009 China League Two season. Unable to gain promotion with the club, he would soon return into assistant coaching with Hangzhou Greentown until on 14 June 2012 second-tier football club Wuhan Zall needed a caretaker manager for the rest of the 2012 China League One season. His appointment would quickly see the club win promotion at the end of the season and he was offered a permanent contract to guide the club in the 2013 Chinese Super League season; however, his time in the top tier was not a success and after the club went on a six-game winless streak, Zheng resigned. In April 2014, he was appointed as the caretaker coach of China national under-20 football team for the 2014 AFC U-19 Championship after Li Bing resigned. In October 2014, China was defeated by Qatar in the quarterfinals and failed to qualify for the 2015 FIFA U-20 World Cup. He joined the managerial competition of China U-20 team in December 2014 but eventually lost to Li Ming. On 15 July 2015, he returned to Wuhan Zall after Zheng Bin resigned from the club.
