Contrary to some comments by columnists/academics, some of the well-known signature acrobatics happened to be unintended consequence. Yam and Loong had/have spine damage from bending forward all the time to accommodate co-stars of very short statue. In 1952 film The Twelve Beauties, height difference was close to a foot when Yam still stood fairly straight in the Fantasy of Heaven of Parting Sorrow, ending scene of Dream of the Red Chamber.
