Zhang Fei is eight feet tall and Guan Yu is nine feet tall. If converted according to modern metric length units and market length units, Liu, Guan and Guan can be described as "super giants". The length of the ancient ruler is not exactly the same as that of the modern ruler. A foot is about 27.65 cm in Qin and Han dynasties and 23-24 cm in Wei and Jin dynasties. One foot in the Tang Dynasty was about 3 1. 1 cm.
In the Song Dynasty, one foot was about 30.72 cm. In this way, the heights of Liu, Guan and Zhang are no different from those of modern people. One foot in the later Han Dynasty is equivalent to 23.04 cm. According to this calculation, Liu Bei's height 172.8 cm, Zhang Fei's height 184.32 cm and Guan Yu's height is 207.36cm..

One of the top ten famous knives in ancient China, Records of Ancient and Modern Knives and Swords, records that when Zhang Feichu, a famous soldier in the late Han Dynasty, was worshipped as a new pavilion Hou, he ordered a blacksmith to take iron from Hongzhushan and forge it into a knife, engrave the "new pavilion Hou" and wear it with him. After Guan Yu died, Zhang Fei went to Wu Dong to avenge his brother. Before sending troops, he whipped the foot soldiers after drinking, which made the Ministry uncomfortable. He sneaked into Zhang Fei's camp at night, beheaded Zhang Fei with a new Tinghou knife, and went to Wu Dong overnight.
