When I was in Beijing, I saw audio versions for Water Margin, Dreams of the Red Mansion and Three Kingdoms. I also listened to the audio novel of Duke of Mount Deer, which was quite good. These are all Mandarin versions.
Anybody saw other Jin Yong audio novels? For those among us who can't read Chinese, it might be a solution. Does anyone know of Cantonese audio novels? I never saw them in HK.
