In the first year of Tang Wude (6 18), Sima Li, the former Sui Yingyang mansion, proclaimed himself emperor in Liangzhou (now Wuwei, Gansu), and according to the five counties in Hexi, he intended to carve up the western part of China. However, Gui Li was very suspicious. When he rose up, he was framed and killed Liang Shuo, an important adviser, which made those who helped him send troops more suspicious and alienated. At the same time, he listened to the demon words of the conference semifinals wizard. Saying "God should send a jade girl from heaven to help you", he recruited soldiers to build a platform, waiting for the jade girl to come down to earth, which was a waste of money and people complained everywhere. Coupled with the bad years, some people even eat each other. Cao Zhen and other good ministers advised him to open a warehouse for relief. However, Xie Tongshi and other officials in Sui Dynasty were unwilling to be ruled by him and deliberately alienated his relationship with relatives. They strongly opposed Cao Zhen's suggestion, saying, "People think that hungry people are not strong, and strong people will not be bothered by hunger. Now that the country is using grain, how can it open a warehouse to help the poor? Cao Zhen wants to express people's feelings, not for the country. Li Gui thought what he said was very reasonable, so he didn't open the warehouse to release grain, which further aroused the antipathy of the military and civilians. Soon, Tang Gaozu tang gaozu sent a Gui Xing to comfort Li Gui, and Li Gui named him the left and right guard general, and asked him how to keep his power. Gui Xing pointed out: Liangzhou is remote and far away. Although it has 65,438+10,000 troops, it is only a thousand miles away, so there is no danger to defend, and it is close to Rong Fan, so it is vulnerable to attack. Now there is Chang 'an in the Tang Dynasty. It is an act of god to attack it unprepared and win it unprepared. If the land of Hexi is raised and attached to the Tang Dynasty, it will be highly praised. Li Gui replied: In the past, Wu Bi called himself the "East Emperor" and there were soldiers on the left side of the river. With so many troops coming from the right side of the river, how can I not be "Xidi"? Although Tang is great, what can he do to me? Afraid of being suspicious, Ann secretly tried to lead Hu Bing and her younger brother An Xiuren to destroy Gui Li. Li Gui went out of the city to fight the Anshi brothers, but his department led Xi Daoxuan to An Xiuren, and Li Gui was defeated and captured. The Hexi land, which has worked hard for several years, collapsed instantly.

Gui Li was too suspicious, didn't need good ministers, and didn't listen to good words, which led to people's distraction. This is the main lesson of his downfall. Militarily, he can't objectively estimate his own strength, can't understand the situation clearly, go against the general trend and bite off more than one can chew. Naturally, he will be defeated and killed in the end. Unification is the general trend. If Gui Li is attached to the Tang Dynasty, he will not only get a whole corpse, but also go down in history to avoid causing untold sufferings.
