In the novel Romance of the Sui and Tang Dynasties, Li Jiancheng and Li Yuanji died in a political struggle. To be specific, Li Jiancheng was killed by the uprising army of the Wagang Stronghold at the end of the Sui Dynasty, while Li Yuanji was killed by Li Jing's army at the beginning of the Tang Dynasty. The reason for this political struggle was that both Li Jiancheng and Li Yuanji had some relationship with the Sui Dynasty, and Li Jiancheng himself was more intimate, which led to the death of the two.
Li Jiancheng's descendants were killed by Li Shimin after the incident at Xuanwu Sect. Li Jiancheng had a total of six sons and five daughters. The eldest son, Li Chengzong, died early. The other five sons, Li Chengdao, Li Chengde, Li Chengxun, Li Chengming, and Li Chengyi, were all killed after the incident at Xuanwu Sect. There was not enough information about the fate of his five daughters. Therefore, Li Jiancheng's descendants did not survive.
😋I recommend My Wife is the Chief to you! The main character traveled through the Tang Dynasty and became a son-in-law who married a chieftain. The Xuanwu Gate incident also changed a little. Li Jiancheng and Li Yuanji were not killed. There was also an interesting detail. The main character, Li Yuan, taught a soul awakening course in the novel, which was equivalent to a principal. I hope you will like my recommendation.

Yes, Li Wanqing was Li Jiancheng's daughter.
Li Shimin's method of dealing with Li Jiancheng was to 'cut the weeds and remove the roots' and execute Li Jiancheng and his family. After the incident at Xuanwu Gate, Li Shi Min had clashed with the Crown Prince and King Qi's armies, and both sides had engaged in a fierce battle. At the critical moment, Yuchi Gong carried Li Jiancheng and Li Yuanji's heads to the Crown Prince and King Qi's army, causing their morale to collapse. After that, Li Shi Min's army entered the Crown Prince's Residence and the Qi King's Residence and took control of them. Li Shimin's order was to 'eradicate the weeds and uproot the roots'. He dragged out all the families of Li Jiancheng and Li Yuanji and executed them. In addition, Li Shimin also executed Li Jiancheng's six sons and Li Yuanji's five sons. This practice had attracted criticism from later generations and was seen as a big "stain" in his life. Therefore, Li Shimin took extreme measures against Li Jiancheng and executed him and his family.
Yes, Li Shimin had shot Li Jiancheng with his own hands.
There was also Long Erdong's "Prince of the Tang Empire: Li Jiancheng", which described the soul-stirring events in Li Jiancheng's short and tragic life. It reflected Li Jiancheng's ability from the side. There were also some time-travel novels. For example, a certain person transmigrated to the Great Sui Dynasty and became Li Jiancheng, the eldest son of Li Yuan, the Duke of Tang. Although Li Jiancheng wanted to be a salted fish in the novel, it also hinted that he had good conditions (such as being born in the Great Sui Dynasty's four noble families, his father was a general, his mother was a female scholar, and his younger brothers and sisters were also extraordinary people). If he wanted to make a difference, he could rely on these conditions to show the characteristics of both civil and martial arts. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Li Shimin had given Li Jiancheng two titles. In the second year of Zhenguan, Li Shimin pursued Li Jiancheng as King of Xi and changed his burial. At the same time, Li Shimin also made Li Jiancheng the hidden crown prince. These actions could be interpreted from two aspects. First of all, Li Jiancheng's posthumous title could clear Li Shimin's name, making his process of seizing the throne more reasonable and legal. Secondly, Li Jiancheng's promotion was also to stabilize the internal situation and ease the conflict with the original Eastern Palace and King Qi's Mansion. This would help stabilize the court and eliminate the negative influence of killing brothers. Li Shimin's act of enfeoffment showed his tolerance and wisdom as an emperor, and at the same time provided important thoughts about power, family, and morality for future generations.
