Been watching the 1979 TVB adaptation of CHOR LAU HEUNG starring Adam Cheng, and noted that this series makes frequent references to Japanese martial arts forms and the ninja arts, which is uncommon for most Chinese wuxia. Gu Long made much greater use of Japanese martial arts and even characters than Jin Yong ever did. Jin Yong looked to the steppes for his heroes' rivals and adversaries, never across the eastern sea to the islands of Japan.
