[2] Rong Hao started his football career with Wuhan Guanggu in 2006, making his debut and scoring his first goal for the club on 27 May 2006 in a 1-0 win against Shenyang Ginde.
By the following season, he began to gradually establish himself as a regular for the club despite usually coming on as a substitute; however, Wuhan were suddenly ejected from the top tier and subsequently relegated during the 2008 season after the club's management refused to accept the punishment given to them by the Chinese Football Association after a scuffle broke out on 27 September 2008 in a 1-1 draw against Beijing Guoan.
[6] On 26 December 2011, Rong transferred to Guangzhou Evergrande along with Zhao Xuri, Li Jianbin and Peng Xinli.
[10] On 13 February 2022, Rong returned to newly-promoted Zhejiang Pro (formerly named Hangzhou Greentown) after 11 years, and he expressed the intention to retire at the club.
On 28 December 2024, Rong held the retirement game with his former teammates Li Xuepeng and Feng Xiaoting in Shandong Linyi Olympic Park.
