Wow interesting, please tell us more. I remember reading in some other forum a few years ago (that HK forum) someone talked about seeing a dragon in HK but I forgot where she saw. She was very serious and again, also looking for others who have seen. Time frame was around 70's I think. Then someone talked about this Lam Tin case, pretty much same as 樓主 described, and that many people saw this fight and this "injured" dragon.
