Hu Di

Hu Di (Chinese: 胡底; 1905 – September 1935) was a Chinese filmmaker and Communist secret agent during the Republic of China era. After the Kuomintang (KMT) began its suppression of the Communists in 1927, Hu worked as a mole in the Kuomintang secret service, together with Qian Zhuangfei and Li Kenong. Chinese Premier Zhou Enlai called them "the three most distinguished intelligence workers of the Party." Hu was executed in September 1935 by the renegade Communist commander Zhang Guotao during the Long March.

Hu was born Hu Baichang (Chinese: 胡百昌) in 1905 in Shucheng County, Anhui Province. He also used the names Hu Beifeng (Chinese: 胡北风) and Hu Ma (Chinese: 胡马).

In 1923, he was admitted to China University in Beijing, where he befriended Qian Zhuangfei and his wife Zhang Wenhua. In 1925, the three secretly joined the Communist Party of China, and they worked closely together. They established the Guanghua Film Company, using filmmaking as a cover for their underground activities. After the KMT's April 1927 massacre of the Communists in Shanghai, and the execution of Communist leader Li Dazhao in Beijing, the three moved to Shanghai, where Hu found work at the Shanghai Film Company. He met the experienced Communist underground worker Li Kenong and introduced him to Qian.
