Just a passing thought - all these images from the Romance of Three Kingdoms (or go watch Red Cliff) show the Chinese in abundance with massive amounts of facial hair. Well that was almost 2000 years ago.
Just think Guan Yu and Zhang Fei. But we're all quite well known as to be comparatively hair-less creatures, when we think of say our European friends, if we look around the Chinese today. Granted we're all well geared with Gillette and the like, but I doubt we had that good facial hair growing power. Or do we? Or has society so decided we must look clean cut?
Something worth finding out more about. I feel like letting the hair flow.
