Chen Hsi-huang, the eldest son of the puppet master Li Tian-lu. Li Tian-lu married into the Chen family in which he became the son-in-law. Under this situation, his eldest son was given the surname Chen. Being the son of the legendary puppet master and the special relationship between the father and the son led them to a mutual knot. In 2009, at the age of 79, Master Chen left the Li family and set up his own troupe, which soon earned recognition all over the world. Nevertheless, this traditional art declined rapidly and Chen found no one to pass on his great skills... Being a fan of puppetry, Director Yang Li-chou named his studio "Back-stage" which means shooting documentary films just like the backstage of the puppetry is to assist humans in revealing this world. The production of "Father" lasted for ten years. It not only recorded the inheritance mission of the eighty-year-old elders, but also explored the conflicts between the two generations. This film shows the master's intellectual skills to give the poppet life on the big screen, trying to inject the unique charm of the traditional puppet show to bring it back to ordinary people.
