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.

Individually, she won two gold medals in the all-around competition and on balance beam, a silver on floor exercise and a bronze on uneven bars.

[citation needed] In 2010, Jiang was selected to compete for the team of women representing China at the 2010 World Championships.

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.

[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.
