As we all know, the "Jinyang Rebellion" in the thirteenth year of the Great Cause (617) was the beginning of the Tang Dynasty. According to common sense, Yuan Cong, who participated in the Jinyang uprising, should be the most trustworthy minister of Li Yuan. However, according to the record of "Datang Entrepreneurship and Living Note", Li Yuan once said to Li Jiancheng and Taiyuan Gongzi when he marched to Chang'an: "However, Jinyang follows me, and it can be described as a person of the same heart, and he is not a fatal person."
There are two translations of "non-lethal people": one is that Li Yuan believes that "Jin Yang Yuancong" is not loyal enough to live and die with himself, the lord, and sacrifice his life for himself; The second is that Li Yuan thinks that "Jin Yang Yuancong" is not professional enough, and his orders cannot be implemented. But either way, Li Yuan does think that "Jin Yang Yuancong" is not reliable enough. What's going on? This ghost talks about the words of a family.
Although Li Yuan was born in the "Eight Pillars of the Western Wei Dynasty", the top of the Guanlong Group, and was the cousin of Emperor Yang of Sui, Emperor Yang of Sui has always had a grudge against Li Yuan. Therefore, Li Yuan was separated from the military for many years during the period of Emperor Yang of Sui, and it was not until after Yang Xuangan's rebellion that Emperor Yang of Sui, who had no one to use, let Li Yuan start to lead troops. It was not until the thirteenth year of the Great Cause (617) that Li Yuan officially served as the Taiyuan garrison who held military and political power.
After Emperor Yang of Sui appointed Li Yuan as the Taiyuan guard, he still did not fully trust Li Yuan, so he appointed Wang Wei and Gao Junya as the deputy guards of Taiyuan. Wang Wei and Gao Junya were both cronies loyal to Emperor Yang of Sui, and both of them had been generals who had led troops before, so they were more familiar with the army than Li Yuan. In other words, Li Yuan was not only under the surveillance of these two people, but also the actual command of a large part of the army under his command did not belong to Li Yuan.
At this time, Li Yuan had two choices: first, give up the rebellion and become a loyal minister of the Great Sui or a handsome man who knows the times; Second, "the greater the wind and waves, the more expensive the fish", he took the risk of personally dealing with Wang Wei and Gao Junya, personally recruiting, forming and training troops and political teams that were truly loyal to him, as was the case with many founding emperors.
However, Li Yuan's choice was to let his second son be responsible for recruiting, building, and training the military and political team loyal to the Li family, and take the relevant risks, and just enjoy the results behind the scenes. In addition to the prince of Taiyuan, most of the people who participated in the preparations for the Jinyang army were middle- and lower-level officials (such as Liu Wenjing) and officers who fled to Taiyuan to avoid the war (such as Liu Hongji), and these people formed the "Jinyang Yuancong".
In terms of the final result, Li Yuan did achieve the success of Jinyang's army with the least personal risk and the lowest personal effort. But "all the gifts given by fate have been secretly marked with a price", and the price of Li Yuan's doing so is that his actual influence in "Jin Yang Yuancong" is very low. For "Jinyang Yuancong", the Taiyuan prince who "came from brown fur" is the lord.
To sum up, Li Yuan felt that "Jin Yang Yuancong" had a problem with his loyalty, and "Jin Yang Yuancong" was also consciously or unconsciously resisting orders directly from Li Yuan and was more inclined to carry out the orders of Taiyuan Gongzi. Because of this, Li Yuan believed that the Yuan Cong heroes who participated in the Jinyang Rebellion were not reliable enough. The contradiction between Li Yuan having the name of the founding emperor but not the fact of the founding emperor was not resolved until the ninth year of Wude.
