The spring and Autumn period and the Warring States Period A period of military necessity, especially King Wuling of Zhao The weapons of Zhao's army were better than those of the Hu people. But most of them were mixed teams of infantry and military vehicles. In addition, officers and men were all dressed in robes, with heavy armour and heavy arrogate, while the cavalry was quick and flexible. However, short clothes and riding shots complement each other. Since Zhou Dai's aristocratic disciples accepted the "six arts" education, "Yu" (driving the carriage) and "shooting" all learned, but not "riding". Even though learning to shoot skills, they should use the "arm clothing" of the cortex (the sleeves of the sleeves) to bundle up the wide sleeves. In the middle of the spring and Autumn period to the Warring States period, all countries used soldiers to fight with chariots. cavalry It does not occupy a leading position. Among the seven males in the Warring States period, Qin, Zhao and Yan were bordered by northern nomadic areas and were deeply harassed by Hu riding. The reason why king Zhao Guojunwang and Zhao Wuling insist on "serving the people, therefore using them" is based on this reality. Wang Guowei pointed out in the text of "Guan Tong Lin Wu Hu Hu Kao", "the beard of Zhao Wuling's king is the archery meter." Liang Qichao in his "ice cream collection six, Zhao Wuling Wang biography" more think that Zhao Wuling's military reform "for riding purposes, and Hu clothing as its means." This is also the same as "Shiji Zhao Shijia": "now Zhongshan is in my heart, North has Yan, East has Hu, West has Lin Hu, Lou fan, Qin, South Korea side, but no strong soldiers to save, is the death of the family. What? I want to be woo. " Hu's introduction also brought many objections at that time, but in Zhao Wuling's "King's different customs, the law of ancient times, the emperors do not attack each other, and how to follow it," the questioning and insistence of the "decree system are appropriate and the clothing equipment is ready for use." The strong power of Zhao has made the allusion of "King Zhao Wuling learn Hu Fu riding and shooting" so far.
