In the seventh year of Daye, Yang Guang began to prepare for the Eastern Expedition to Goguryeo, recruiting soldiers and grain and grass, but there were many people who were not willing to go so far to fight, of course, conscription was mandatory, not that you could not go without going, so some people embarked on the road of escape for this purpose, such as the eldest son Shunde.
The eldest grandson Shunde was the uncle of the eldest grandson Wuji and the empress dowager, and the eldest grandson family was still a relatively large family during the Northern Zhou Dynasty and the Sui Dynasty, and the eldest grandson Shunde was originally also an official in the Sui Dynasty, but the official position was relatively small, only a right guard. When Yang Guang was marching on the Eastern Expedition, the eldest grandson Shunde was also among them.
However, the eldest son Shunde was not willing to go to Liaodong to fight, he only wanted to be a minor official in peace and stability. In order not to fight, the eldest son Shunde ran away, and he ran to Taiyuan and lived in Li Yuan's home. The eldest grandson Shunde and Li Yuan had been good friends before, and his niece was also married to Li Yuan's second son, Li Shimin, which was a step closer.
The eldest son Shunde lived in Li Yuan's place for a long time, until 617, When Li Yuan felt that the time had come, he also prepared to raise an army, and Li Shimin, Liu Wenjing, Changsun Shunde, liu Hongji, and others began to recruit troops to prepare for Li Yuan's army.
They gathered more than 10,000 people in a very short period of time, and then trained these soldiers separately, and Li Yuan's operation made his deputies, Wang Wei and Gao Junya, who were also sent by Yang Guang to monitor Li Yuan, suspect. It should be known that although Li Yuan was deeply hidden, the eldest son Shunde, Liu Wenjing, Liu Hongji and others were all guilty people, and Li Yuan not only did not punish them, but also did not send them to Yang Guang, but instead let them train soldiers, which had the meaning of great reuse.
Therefore, Wang Gao and his men concluded that Li Yuan's ambitions were not small, but the two were more unlucky, and the plan to get rid of Li Yuan was known to Li Yuan in advance, and in turn, wang Gao and the two people were solved first, and the eldest son Shunde and Liu Hongji were naturally the main forces to solve Wang Gao's two people.
Later, Li Yuan officially raised an army, and the eldest son Shunde became the unified army and made many military achievements. At that time, the general Qu Tutong of Zhenshou Hedong met Liu Wenjing and Changsun Shunde at Tongguan. Qu Tutong was invincible, but he was unwilling to surrender, and finally after Li Yuan attacked Chang'an, he chose to lead his troops to Luoyang to defect to Yang Tong, but the eldest son Shunde did not give Qu Tutong this opportunity, and he chased to Taolin and tied Qu Tutong to Chang'an.
After Li Yuan ascended the throne, Changsun Shunde became the general of Zuo Xiaowei and was made the Duke of Xueguo, because of the relationship between Empress Changsun, Changsun Shunde was on li shimin's side, although the historical records do not record what role he played in the rivalry between Li Shimin and Li Jiancheng, but he participated in the Xuanwumen Change in 626.
The Old Book of Tang records:
"In the ninth year of Wu De, he negotiated with Qin Shubao and others to build the Yu Dang at Xuanwu Gate."
Therefore, after Li Shimin ascended the throne, the eldest grandson Shunde had 1200 households to eat, and his peers were Luo Yi, Chai Shao and Li Xiaogong. Not only that, Li Shimin also gave the eldest grandson Shunde a palace maid and allowed him to stay in the inner province.
Such a reward is not something that anyone can have, in addition to the merits of the eldest grandson Shunde himself, naturally part of the reason is because he is the uncle of the eldest grandson empress, and he is also a foreign relative. But even though the eldest grandson Shunde was already a high-ranking lord, it was reasonable to say that there was no shortage of property, but he was just "fed silk".
This incident occurred shortly after Li Shimin ascended the throne, when the eldest son Shunde was a slave for personal gain, accepted the silk veils of others, and Yousi impeached the eldest son Shunde. Li Shimin was very angry, he did not expect the eldest son Shunde to hit him in the face like this, and he said to the people around him:
"Shunde is a foreign relative, the merit is the yuanxun, the high knighthood is thick, enough to be called rich." If you can diligently read the ancient and the modern, learn from yourself, and benefit our country, you should have a house with you. Why not obey the name, and be greedy and smelly! ”
He hated the meaning of iron not steel, and after Li Shimin vented, he had to think about how to dispose of the eldest son Shunde, according to the law, this is not a minor sin. However, considering the identity of the eldest grandson Shunde, who was both a founding hero and the uncle of the eldest grandson empress, it was reasonable that Li Shimin could not punish him severely.
Thinking about it, Li Shimin decided to give the eldest son Shunde dozens of silk horses in public to shame him. However, such a punishment made many people dissatisfied, Dali Shaoqing told Li Shimin
"Shunde has perverted the law and received wealth, and his sins are unforgivable, so why give them silk?" ”
Li Shimin said:
"The spirit of human nature is more silk than torture; if you are not ashamed, a beast's ear, what is the benefit of killing!"
This means:
If the eldest grandson Shunde had a sense of shame, then after receiving these dozens of silk horses given by Li Shimin, he must be very ashamed, and he would be eager to find a seam to drill into, which would be more embarrassing than killing him, and he would correct it in the future. And if he has no shame, even if he kills, what is the point?
This remark is not unreasonable, but even if Li Shimin is trying his best to save the life of the eldest son Shunde, then what kind of reaction did the eldest grandson Shunde react after receiving such a reward? He did not seem to reflect on himself as Li Shimin thought.
This also made Li Shimin very angry, coupled with the good relationship between the eldest son Shunde and Li Xiaochang, and soon after, the eldest son Shunde was dismissed from office, and the knighthood was also withdrawn and became an idle person. It is precisely such an experience that makes the eldest grandson Shunde think bitterly, and after being appointed again, the eldest grandson Shunde is like a new person, according to the Old Book of Tang, it is "the government of The Ming Dynasty in Li County".
