1984, Sammo Hung and Cen Jianxun founded Debao and produced a series of "Senior Sisters", which initiated the trend of female action movies. This four-part film series is a classic female action film in the late 1980s. I haven't seen the best first film yet. No matter the plot, fighting, cast and performance, it is absolutely satisfactory. Especially guest performances, such as Sammo Hung, Ceng Zhiwei, John Chiang, Richard Ng and Feng Cuifan. , impressive. Even Tsui Hark is a guest, and "Special Guest Tsui Hark" appears in a prominent position on the staff list, occupying the whole screen. I don't think it's a guest appearance at all. There are too many scenes.

The series "Senior Sisters" can be said to be the forerunners of the internationalization of Hong Kong-made films, and each film was shot in a different country. This film focuses on the interest disputes between the international Bonnie and Clyde and Japanese jewelry merchants, with suspense and action.

The first part of this series, Yujie, is the representative work of Debao Company. There are more than N members in Hongjiaban, and Hou Yaozong, Qian Jiale and others act as small thugs. Yang Ziqiong and cynthia rothrock were in charge of wonderful movements, but after all, Yang Ziqiong became a monk halfway and was eclipsed by the professional cynthia rothrock. However, from the beginning of the movie "Royal Sister 3: Bonnie and Clyde", the starring role was changed to Cynthia Khan, and Cynthia Khan's performance in the film was no less than that of Yang Ziqiong, and even slightly surpassed it.
