Zhao was born Li Kuntai (李坤泰) to a rich family of Sichuan Province in October 1905.

She joined the Communist Party of China in 1926.
In September 1927, she went to the Soviet Union to study at the Moscow Sun Yat-sen University.
She married her comrade Chen Dabang (陈达邦).
She returned to China in the winter of 1928, and engaged in the underground Communist work in Shanghai, and then in Jiangxi Province.

After the Mukden Incident, she was sent to northeast China to start up struggles against the Japanese occupation.
She changed her name as Zhao Yiman to avoid implicating her family.

In November 1935, the Imperial Japanese Army and the Manchukuo troops encircled the 2nd Regiment of the 3rd Army of the Northeast Anti-Japanese United Army.
Zhao Yiman, who was political commissar of the regiment, was seriously wounded.
Several days later, the Japanese found Zhao in a farmhouse where she stayed.
In the ensuing fighting, she was wounded again and captured.
Zhao was tortured after an argument with the questioners.
In view of her political value, the Japanese sent her to a hospital to receive treatment.
In the hospital, Zhao persuaded Han Yongyi, a female nurse, and Dong Xianxun, a guard, to help her escape.
However, she was recaptured not far from the guerrilla base and suffered further torture due to her attempted escape.

She was executed by the Japanese on 2 August 1936.
 Before her execution, she wrote a farewell letter to her son Ning'er (formal name Chen Yexian), which has survived.

The guard, who helped Zhao to escape, Dong, soon also died in the prison after being tortured.
