She is the 2008 Chinese all-around senior National Champion[1] and a member of the gold medal-winning People's Republic of China team for the 2008 Summer Olympics.

Soon thereafter, in 2003, she joined the National Training Camp for a stint before it was forced to disband due to the outbreak of the disease, SARS.

As a result of the injury, Chinese coach Lu Shanzhen also decided to pull Jiang from the vault rotation in the team finals, replacing her with Deng Linlin 20 minutes before the competition began.

She won a team gold medal with her teammates, Cheng Fei, He Ning, Zhou Zhuoru and Liu Nanxi.

She also placed 5th on uneven bars, but did not advance into the final due to the 'two per country rule' while her teammates He Kexin and Huang Qiushuang qualified first and second.

Despite falls and mistakes made by Jiang and her teammates, the Chinese women team managed to secure a bronze medal, following Russia and the United States.

On March 24, 2011, Jiang is set to compete in Canada's Wild Rose Cup along with newcomers and juniors Huang Huidan and Shang Chunsong.

[19] In early 2008, fellow Chinese gymnast Yang Yun, admitted on national television that she was 14 years old when she competed in the 2000 Sydney Olympic Games.

[20] Consequently, there was frequent speculation that members of the Chinese women's gymnastics team were 14 years of age or under,[21] violating the minimum age requirements of Fédération Internationale de Gymnastique (FIG), the governing body of the sport, that requires gymnasts to be 16.

[22][23] The New York Times claimed that official media and some official Web sites in China, including that of the State General Administration of Sport, listed Chinese gymnasts' details which indicated that Jiang, He Kexin and Yang Yilin may have been as young as 14.

[21] In response, Chinese officials claimed the discrepancies for He Kexin were caused by paperwork errors when the gymnast switched teams.

[22] On 23 August, further pressure led the FIG to request additional documentation on five of the six athletes on the Chinese team.

[31] Having been satisfied with the proof of age received from the Chinese Gymnastics Association, the FIG ended the investigation on 1 October 2008, concluding that He and her teammates were eligible to compete.
