Gao Hongbo
Zeng's performances for Henan Jianye at the beginning of the 2009 season would see the Chinese national team manager Gao Hongbo call him up to the international set-up for the first time. He made his debut against Iran in a friendly which China won 1-0 on 1 June 2009. After that game, he would become the national team's second choice goalkeeper behind Yang Zhi and be included in the squad that won the 2010 East Asian Football Championship before being included in the 2011 AFC Asian Cup squad.
