In recent months, we've had discussions about how surprisingly ignorant wulin people generally were even about the most accomplished and powerful wulin people of the time. For example, despite the Greats being the most powerful and important martial artists in wulin during L/ROCH, there were *scores* of people who were ignorant (some of them rather surprisingly so) of the Greats and their accomplishments.
For this reason, I find Lee Mok Sau's erudition on wulin affairs very impressive. Not only was she very familiar with the histories of all the Greats, but she knew the details of the lives and histories of more obscure martial artists such as East Heretic Wong Yerk See's students (who had died or retired from wulin YEARS before Lee Mok Sau left the Ancient Tomb). For someone who had only been active in wulin for around a decade when ROCH began, that's an amazing awareness of wulin lore (including the obscura) considering how ignorant wulin in general seemed about its own luminary figures.
