Zhou Yajun began his football career with the various Shanghai Shenhua youth teams and took part in the squads that trained in Brazil, however instead of immediately continuing with his football career Zhou Yajun would instead continue with his studies and go to Donghua University where he still played football as a goalkeeper. Surprisingly he would find himself continuing to play in goal due to injury and suspensions to the other goalkeepers and by the end of the season he had played in 12 league games.
Zhou Yajun's progression within the Shanghai Shenhua's football team was short lived when they merged with local football team Shanghai United F.C. and with the influx of players he found himself immediately dropped from the newly formed team throughout the 2007 league season.
