Song Dynasty was the most cowardly dynasty in history. Although the Song Dynasty was brilliant and famous officials came forth in large numbers, it still did not help the weakness of the Song Dynasty. In addition to the reasons analyzed by historians, there is at least one important reason: the Song Dynasty failed to control Yanshan Mountain and the Great Wall, and there was no barrier in the northern border defense, which was always directly exposed to the fierce attack of the northern cavalry. There is no buffer zone between nationalities with completely different lifestyles, which leads to unprecedented sharp ethnic contradictions. During this period, countless touching folk stories were produced, among which Yang Jiajiang was the most famous.
/kloc-at the end of 0/0, Song Taizong Zhao Guangyi realized that it was necessary to recover Yanshan Mountain and control the Great Wall. After successively destroying Southern Tang, wuyue and Northern Han countries, they sent two armies to northern expedition Liao. East Road, led by Cao Bin, a general who shocked the ruling and opposition in the Southern Tang Dynasty, took Beijing directly. It was called Yanjing at that time. Beijing is the temporary capital of Liao, and the official capital is north of the Great Wall. The West Road, led by General Pan Mei (the legendary Pan Renmei), set out from the central part of Shanxi and attacked the northern part of Shanxi, intending to recover the Great Wall in the northern part of Shanxi. Yang Ye (the legendary Yang Jiye Laoyanggong Bell) is the deputy commander-in-chief of the marked army. Unexpectedly, Cao Bin can make Li Yu, queen of the Southern Tang Dynasty, resign from the temple in panic, but he can't compete with Xi cavalry of the North and South Mansion led by Xiao Taihou. [The King of the Southern Courtyard here is not Hero Qiao] Poor 100,000 elites were wiped out by Liao in the Baigou River area not far from Beijing, and General Cao Bin fled back with only one man and one horse! I guess Cao Bin must be a martial arts expert, and his martial arts skills are by no means weaker than those of Zhao Yun, a famous player in the Three Kingdoms, so he can look down on Yang Jiajiang.
