Zhao Hejing started his football career with top tier side Chongqing Lifan and would make his league debut for the team on 3 July 2005 against Sichuan Guancheng where he conceded a penalty that led his club losing 2-1. Despite the defeat, Zhao would gradually establish himself as a regular. However, by the end of the 2006 season, he was part of the team that was relegated.
His return to the top tier often saw the club struggle within the league and Chongqing were once again relegated at the end of the 2010 season. Before the 2011 season, Zhao would transfer to second tier side Dalian Aerbin for 2 million yuan. On 3 January 2014, Zhao transferred to fellow Chinese Super League side Beijing Guoan on a free transfer.
