Li Yuan is different for Liu Wenjing, Liu Wenjing, as a great hero of Taiyuan's army, is a matter of course for him to be promoted to the rank of knight. At the beginning of the Tang Dynasty, Liu Wenjing was appointed as Nayan and became the prime minister, and at the same time, he also got the privilege of "forgiving two deaths" together with Li Shimin and Pei Lian, the kings of Qin. But he did not sit with Li Yuan in the upper court, and the lower court treated him in the palace. Moreover, he went out and lost the battle, and Li Yuan decisively removed him from his post, without taking into account his feelings at all, and giving him some feelings that they had fought together in the most difficult time.

When Xue Ju, the overlord of Western Qin, invaded Jingzhou (now Jingchuan, Gansu), Li Yuan sent him and Yin Kaishan to assist Li Shimin to clean up Xue Ju, Li Shimin had dysentery and could not fight with Xue Ju, so he asked Liu Wenjing and Yin Kaishan to be patient first, and then clean up Xue Ju when the time was ripe.

Liu Wenjing returned to Chang'an, Li Yuan did not give him a good face, and ruthlessly dismissed the official title and demoted him to a commoner, until Li Shimin pacified Xue Ju, Li Yuan restored his official title.

The two former good brothers went out and lost the battle, and Li Yuan treated them differently, which really made Liu Wenjing feel distressed!

Faced with this situation, Liu Wenjing was a little overwhelmed in her heart, and she had to complain a few words before she could vent her grievances, which was understandable.

In the second year of Wude (619), Liu Wenjing followed Li Shimin and guarded Changchun Palace (in present-day Dali, Shaanxi).

He thinks that he can be above Pei Lian, and he has repeatedly made military achievements, but Pei Lin can rise to the top, and is reused by Li Yuan, and his status is far inferior to Pei Lian, so his heart is very unbalanced, and he often disagrees with Pei Lin when discussing the government, and he has to oppose everything that Pei Lin agrees with; What Pei Lin agreed, he opposed. Pei Lin was naturally unaccustomed to facing this pole spirit, and the contradiction between the two deepened.

Moreover, Liu Wenjing admonished many times, but Tang Gaozu Li Yuan did not accept it, and "neglected it", and became suspicious of it, Liu Wenjing must be unhappy, and held a grudge against the favored Pei Lian, thinking that he was provoking in the middle.

Once, Liu Wenjing and his brother Liu Wenqi ate and drank, and after a few glasses of wine, they remembered that Li Yuan's favorite minister Pei Lin was not a taste, and with a little drunkenness, he pulled out his saber and slashed at the pillar in the hall, and said indignantly with a red face: "One day, I will cut Pei Lin like this pillar." ”

Saying such drunken words, it must have been really depressing for a long time.

It is estimated that Liu Wenqi had a nervous breakdown and hallucinated, and felt that a little demon had come to the house and wanted to hurt him, so he summoned a wizard to dance with a sword in the night, doing things to drive away the demon. In the dead of night, whoever sees this scene will feel terrible and want to be in trouble.

At this juncture, Liu Wenjing had a concubine who had fallen out of favor, and she told his brother about this glittering matter, and asked him to tell the emperor that Liu Wenjing was plotting rebellion.

- A man cannot easily offend a woman who loves him, otherwise the result will be very serious, and it may be hated by love, this is a living example.

Tang Gaozu Li Yuan heard that Liu Wenjing, who had never been fanciful to him, had rebelled, which was a very terrible thing, and he would only rest assured that he would destroy her, so he handed Liu Wenjing over to Pei Lin and Xiao Yu for interrogation.

Pei Lin participated in the interrogation, and Liu Wenjing was decided. Pei Lin couldn't get used to him for a long time, and heard that he was going to cut him to death like a pillar, and finally waited for the opportunity to take revenge.
