Is it reasonable to return to Zhao after a complete wall in history?

In 3 1 1 BC, after the death of King Shang of Qin (King Huiwen of Qin), the prince succeeded to the throne, that is, Qin Wuwang. Because the reign time was too short to leave children, Wang Jiwei, the younger brother who was held hostage in Yan State at that time, succeeded to the throne ... At the same time, in the eastern part of Qin State, Wang Yong of Zhao State (that is, the Wu Tomb of Zhao State) began the reform known as "Khufu riding and shooting". On the surface, this is only a technical military reform, but its essence is to ban aristocratic feudal private soldiers and let the state dispatch and train troops in a unified way. The reason why it was changed to "Khufu" has nothing to do with the convenience of fighting. It can be seen from the site of Qin Terracotta Warriors and Horses that the soldiers' costumes at that time were actually very capable, and there was no problem of "wide robes and big sleeves". As for cavalry, it appeared in China's military sequence as early as Shang Dynasty, and in the early Warring States period, cavalry began to replace chariots in large numbers, which is nothing new for Zhao Wangyong in the middle and late Warring States period. I'm afraid the real purpose of "Khufu riding and shooting" is to break the ritual and music system since the Western Zhou Dynasty, and to break the shackles of the aristocratic system on China people in the ideological level. In the etiquette system of ancient China, "dressing" has an extraordinary significance. Not everyone is qualified to wear a wide robe and big sleeves, but behind it is a strict hierarchy and privilege system. /kloc-more than 0/400 years later, Peter the Great of Russia also carried out a profound reform, and his means also began with "changing clothes"-Peter the Great ordered the Russians to shave off their traditional beards, give up their robes and wear lean western European clothes instead. Zhao's reform once refreshed Zhao's situation. Zhao expanded to the northwest and captured Yuzhong (now the Hetao area at the junction of northern Shaanxi Province and Inner Mongolia Autonomous Region), thus forming a condescending geopolitical pressure on Qin State. Later, Zhao conquered Zhongshan State (now in Hebei Province), two northern grassland tribes, Beiji and Loufan, and greatly pushed its territory to the northwest. Zhao Wangyong also ordered the construction of two Great Walls to prevent Hu Lin and Lou Fan from going south. The first one is in Wujiahe and Langshan in Inner Mongolia, and the second one is in Urad Qianqi, Baotou and Hohhot in Inner Mongolia to Zhangbei in Hebei. After the reunification of China, the two Great Walls were rebuilt by Qin Shihuang and brought into the Qin Changcheng system. On the original land of Loufan, Zhao Jian established Yanmen County (now between Shanxi, Shenchi in northern Inner Mongolia, Wuzhai and Ningwu) and Yunzhong County (now between the south of Daqing Mountain in Inner Mongolia, the south of Yellow River and the north of Great Wall), and the original Yuzhong. At this point, the state of Zhao posed a huge geographical threat to the northern part of Qin.
