Sun Quan, Sima Yi and Sima Yan, these three people together said that Sun Quan had blue eyes and a purple beard. Just green eyes and a purple beard. The upper body is particularly long and the lower body is particularly short. The color of eyes and beard proves that Sun Quan's lineage may not be pure China, and the proportion of upper and lower parts is actually nothing special. Is Sun Quan a short-legged tiger? But the ancients thought that being long and short was the material of being a monarch, which could appease subordinates (good people) and do their own sovereign duties well.
