To make "The Matrix" (1999) and its sequels, the Wachowski brothers hired legendary Hong Kong action director Yuen Woo-Ping as a fight choreographer so Michelle Yeoh's scorpion kick from Mr. Yuen's "Tai-Chi Master" (1993) became Carrie-Anne Moss's scorpion kick in "The Matrix Reloaded" (2003).
In 1985, along with business partner Roy Chung Chi-ping, he founded Techtronic Industries in Hong Kong, which had six employees and focused on producing rechargeable battery packs in hand tools.
