Shandong Luneng's youth team before moving to the senior team and would eventually earn his senior team debut on 29 March 2006 in a game against
Shenzhen Kingway. He would later score his first senior goal against
Liaoning Hongyun on 27 September 2008 in a 4-2 victory. With Shandong, he would twice win the league and the
