Qian Zhuangfei was a Chinese doctor, film director and a secret agent for the Chinese Communist Party. After the Kuomintang (KMT) began its suppression of the Communists in 1927, Qian infiltrated the KMT secret service, and in 1931 intercepted a telegram reporting the arrest and defection of the Communist leader Gu Shunzhang. His quick reaction allowed the Communist leadership in Shanghai to evacuate, and he was credited with saving the lives of top leaders including Zhou Enlai, later the Premier of China. Zhou called Qian and his fellow agents Li Kenong and Hu Di "the three most distinguished intelligence workers of the Party." Qian was killed in 1935 during the Long March. He was the father of Li Lili, one of China's most popular film stars in the 1930s.

Zhou Enlai was a Chinese statesman, diplomat, and revolutionary who served as the first Premier of the People's Republic of China from September 1954 until his death in January 1976. Zhou served under Chairman Mao Zedong and aided the Communist Party in rising to power, later helping consolidate its control, form its foreign policy, and develop the Chinese economy.
