One thing I noticed from DGSD '81: early on, Deun Jing Tsun's four bodyguards were unable to take on any of the Great Evils one-on-one. Later in the series, however, it seemed that each of the bodyguards was able to handle at least Divine Crocodile or Wan Chung Hok one-on-one (Yip 2 Leung and Deun Yin Hing were a different matter, of course).

Did the bodyguards improve their martial arts during the course of DGSD?
