i asked some chinese elders that i know what the character "biu" or "biao" means and they couldn't give me a very good description. the idea i got however, is not of a "cub". the mandarin term "biao han" means fierce/powerful/tough man, it is rarely seen as a character by itself. when described, i was getting the idea that it was some sort of long lost wild cat that was in china at some point.
