I recently watch HSDS 2000 and when they introduced Cheng Kun they referred to him with a title. Rough pinyin is Wung Luen Pik Lik Sau. I remember a long time ago I watched a series which has a character (antagonist I believe), use a similar named palm called Wung Luen Pik Lik Jeung which was his trademark palm. The protagonist on the other hand learns a martial art called Wung Luen Shen Gong.
Does any of this ring a bell with anyone? Especially the series I'm talk about.
