Ju Shou commanded a great army, saying, "You are a white horse and a fine colt. When you break the Lu, the Lu is called General White Horse. Therefore, we chose the elite 3,000, took the white horse, and called it' White Horse Righteousness' to actually ban the guards. " In the Battle of the Three Kingdoms, "White Horse and One Clever" was just a meteor, and it was an elite cavalry unit in Gongsun Zan. Unfortunately, it was only brilliant for a short time, and it was annihilated by Yuan Shao's general Juyi in the battle of the side bridge. Gongsun Zan was famous for his bravery and heroism in the battle with the northern conference semifinals. He is good at using a double-headed iron spear. The Book of the Later Han Dynasty says, "Chang Jun and dozens of people who are good at shooting all ride white horses, thinking that they are on the left and right wings, claiming that' white horses are just obedient'". Wu Huan told each other more and avoided the history of Changbai horse. After that, Baimayi expanded into a large-scale army. It was once a great earthquake beyond the Great Wall. Wu Huan is a painting in the shape of a horse. He patted it with a galloping horse. Long live the winner. Since then, Lu has walked out of the Great Wall. ".It's a pity that Gongsun Zan met Juyi, the nemesis of his life, and Baimayi never recovered. "... Jun saw his serenade and set off to dance. All the volunteers stood motionless under the shield, and within dozens of steps, they all got up at the same time, raised dust, shouted, threw heavy arrows at the front, and fell down in the middle, and Chen Zan's office was the first to stab Yan Gang's house in Jizhou. After the defeat of the army, he rode away and never returned to the camp. "This is a typical example of using crossbows to break cavalry. It is worth mentioning that it is mentioned that Zhao Yun was originally one of the white horses to obey, and it is also considered that the seeds are reserved for this elite army. According to the legend of heroes, when Yuan Shao heard that the white horse obeyed, there was a conversation-Shao Xiao said, "There is a white horse obeying, and there is a' spurge'. Are you scared? Hu He: "Hey, I broke it for myself! "Look around and say nothing.
