Houshuge
Meng Zhixiang, the founder of Houshu, turned out to be a general of Shu before the demise of the later Tang Dynasty. Later, after the civil strife in the later Tang Dynasty, Meng Zhixiang took the opportunity to stand on his own feet and set up the Houshu court. By the time Song Taizu attacked Shu, the post-Shu regime had been established for 30 years. Meng Chang, the late ruler of Shu, was in power at that time, not an agent. When he acceded to the throne when he was young, he killed a general like Li, who relied on merit and arrogance, and shocked the ruling and opposition parties. Later, Qin, Feng, Jie, Cheng and others were captured, and the former Shu also had a place. Although the rule in his later years has gradually become extravagant. However, the post-Shu regime is in a peaceful corner, with fewer wars and more stable people's lives.

In addition, it should be pointed out that when Song Taizu sent troops to Shu, there were not many troops. The Shu army used as many as 100,000 troops before and after, but it was more than the attacking Song army. Coupled with the favorable terrain, it could have won the first world war.
Therefore, the rapid demise of post-Shu has nothing to do with the yellow power and the disparity in strength.
Song Jun strategy
Song Jun adopted a two-way attack strategy to destroy Shu. In 964, Song Taizu sent 50,000 troops to attack Shu in two ways. Wang Quanbin led the North Road Army to ride 30,000 troops from Fengzhou (now northeast of Fengxian County, Shaanxi Province) south along Jialing River. Liu Guangyi led the east road to ride 20 thousand from Guizhou (now Zigui, Hubei Province) to the river. Divided into converging attack and attacking Chengdu.

Wang Quanbin attacked Xingzhou first, and the Shu army was defeated, burning the plank road and dropping the insurance. Wang Quanbin divided his forces to attack the northern part of Shu, and at the same time built a plank road to take Luochuan. After Shu was defeated, he retreated to Jianmen. Later, some ministries will point out that there is a road in Jiange called Su. On the one hand, Wang Quanbin stormed the sword gate, on the other hand, the dispatch department will implement the strategy along the road. Form a front and rear attack.
After Shu, the general panicked, only took some generals to guard the sword gate, and led his main force to surrender to Hanyuanpo. Finally, it was attacked by the Song Dynasty. At that time, the Northern Song army attacked Shu along the Yangtze River, broke through Kuizhou, Wanzhou, Zhongzhou and Suizhou, and advanced to Chengdu. When Meng Changjun saw that the tide was gone, he surrendered to Chengdu.
The overall strategy of the Shu army is quite chaotic. For example, when the Shoujiang of Jianmen heard that Song Jun besieged Jianmen before and after, he actually led the main force to evacuate. Kuizhou Shoujiang should have led the army to stick to it, but he rushed out. However, it can be said that the reason why Shu was not as powerful as Song was, of course, because in this battle, the fighting capacity of Shu's army, which had been content with the world for a long time, was far less than that of the army that had been conquering for many years. The retreat and loss of the Shu army is its obvious performance.
