Ming Lou in the TV series "The Pretender", because of his multiple identities, he can easily wander between the major forces, among which, because of the transmission of useful information for the CPC Central Committee, all of them have attracted a lot of powder. In fact, in real life, the character of Ming Lou also has a prototype, he is Yuan Shu, a five-fold agent who was active in Shanghai's political circles and literary circles in the 1930s and 1940s.

In 1911, Yuan Shu was born in a declining eunuch family in Puchun, Hubei Province, his father's old league member, and later served in the Nationalist government, and after Yuan Shu returned to China to study in Japan, he founded the "Literature and Art News" weekly magazine in Shanghai, although he was ordered to stop publishing the news of the murder of the five martyrs of the Left League, but he was concerned by Pan Hannian, an underground intelligence officer of the Communist Party of China, and became an underground intelligence officer of the Chinese Communist Party. Under the guidance of the organization, Yuan Shujing introduced him to Wu Xingya, director of the Shanghai Municipal Social Bureau and head of the Central Unification Bureau, and smoothly entered the internal affairs of the Central Unification. In 1933, he successfully became the head of the intelligence unit of the "Gansha" and a reporter for the Xinsheng News Agency. With the identity of a journalist as a cover, he met Eiichi Iwai, the vice consul of the Japanese consulate in Shanghai, at a press conference of the Nanjing government, and after learning about Yuan Shu's special status, he lured him to become a Japanese intelligence officer with a communication fee of 200 per month.
In April 1937, Yuan Shu found another opportunity to join the well-known Qinghong Gang in Shanghai Beach, and sat on an equal footing with Du Yuesheng and other brothers of the "Tong" generation. After the outbreak of the War of Resistance Against Japan, Dai Kasa, director of the Military Command bureau of the National Government, wanted to find an intelligence officer who was closely related to Japan and familiar with Japan, and under the recommendation of Du Yuesheng, Dai Kasa found Yuan Shu, who at this time already had a five-fold identity, which was also extremely rare in the history of Chinese and foreign intelligence.
After the liberation of the whole country in 1949, he finally ended his five-fold intelligence status and went to the intelligence department led by Li Kenong. However, during the investigation, he accidentally went to prison and sentenced him to 12 years in prison. He was released from prison in 1967, catching up with the Cultural Revolution, followed by another eight years of imprisonment. In 1975, he was released again, he was sent to a labor farm for rehabilitation, and after Pan Hannian was rehabilitated in 1982, Yuan Shu was officially acquitted. Yuan Shu in 1987 was mentally deranged and often cried. On November 26, he completed his legendary life in Beijing.
