Just added this portrait to HKMDB

Ku Lung produced several movies in the last 70s and first 80s, some of them written and/or directed by himself, but mostly in Taiwan.

Some of them are "Wanderer With Nimble Knife", "The Romantic Double Rings" (1979), "Chu Lio Hsiang and Hu Tieh Hua", "Awe Inspiring Weapon" (1980).

Sorry never heard about "Bao Sian"
