The night chase near the beginning of "CTHD", where Shu Lien pursues Jen across the rooftops references a very similar aerial night-chase in "Yong Chun" (Pok To after Flying Monkey). Both films also have feature bandit-chief characters who capture fierce woman, only to fall in love with them. Michelle Yeoh and Pei-Pei Chang appear in both films as a master fighter.
Like the samurai, Wing Chun is the sole (and unappreciated) defense of a small village against an army of bandits. Also, the river fight scenes reference a battle in "Seven Samurai".
