Yin Mingzhu

Aside from her work as an actress, Mingzhu is also known for her work as an investor and production coordinator. During the three-year period that her mother forbid her from acting, Mingzhu became an investor by investing in the Shanghai Shadow Play Company. When bankruptcy threatened the future of the production company after the failure of Imperial Concubinebine of Yang, Mingzhu invested her own personal savings into the company to save it. In 1932, during the Second Sino-Japanese War, the Shanghai Shadow Play Company was destroyed. Both Mingzhu and Duyu were out of work until 1934 when Mingzhu invested in and set up the Shanghai Talkie Company for her husband.

Before finding fame in the film industry, Mingzhu was known as "Miss. F. F.", which stood for "Miss Foreign Fashion". She was a sensation within the elite society of Shanghai. At the age of seventeen, Mingzhu met director Dan Duyu at a party and the pair began working together, making films. As Mingzhu and Duyu started to establish a work relationship, the pair fell in love, despite Mingzhu being married to a Frenchman. Mingzhu vowed to remain loyal when her husband was redeployed back to his home country. After he failed to return to Shanghai, Mingzhu married Duyu in 1926. While Yin Mingzhu starred in about half of the 30 movies directed by Duyu, most are believed to be lost films. Mingzhu, and Duyu's relationship was unique to that of any other couple in the film industry. Traditionally, it was the director, or husband, that made the actress, or wife, famous. In the case of Mingzhu and Duyu, it was widely recognized that Mingzhu's fame brought Duyu his own fame and success. The couple later moved to Hong Kong, where Mingzhu died in 1989.

Mingzhu began her career as an actress in the silent film era when she met Duyu. In 1921, Mingzhu joined Duyu's Shanghai Shadow Play Company, where she starred in Duyu's Sea Oath. Reviews for Sea Oath praised Mingzhu for her performance as a first time actress. However, Mingzhu's career was in danger of ending after the publicity Sea Oath as her mother forbid her from making any more films. In 1925, three years after Mingzhu left the film industry, her mother gave in and allowed her to star in Duyu's "philiosopical film", Some Girl. Mingzhu starred in many other productions after this, some directed by Duyu, and some by other Chinese directors and filmmakers. Some of Mingzhu's most famous work as an actress includes The Spider Cave, A Dream of Red Mansions, Oriental Nights, The Golden Age, and, Peach-Blossom Dreams.
