What achievements did Li Jiancheng have?

Yes, Li Shimin had shot Li Jiancheng with his own hands.

Li Shi Min had many achievements. First, he had successfully quelled many internal conflicts and stabilized the situation in the Tang Dynasty. His prestige in the court had also increased greatly. Secondly, he actively carried out external expansion and conquered many neighboring countries, finally realizing the great cause of the Tang Dynasty's unification. He had also personally conquered Goguryeo, capturing many cities and migrating 70,000 people to China. In addition, he also defeated the leader of Xue Yantuo, Duomi Khan, put down the anti-Sui rebellion in Shanxi, and defeated the Turks and other independent forces. He was outstanding in military affairs, good at formulating strategies and tactics, and achieved amazing victories in many battles. He also adopted a series of policies to consolidate his ruling position, such as all-embracing, implementing the legal system, reducing the tax burden, and building water conservancy projects. His leadership and achievements earned him the honorific titles of the wise ruler and the Heavenly Khan, which laid an important foundation for the flourishing Tang Dynasty.

Yes, Li Jiancheng and Li Yuanji both had descendants. Li Jiancheng had four sons: Li Chengdao, King of Anlu, Li Chengde, King of Hedong, Li Chengxun, King of Wu 'an, and Li Chengzhi, King of Runan. Li Yuanji had three sons, Li Chengye, Prince of Liang, Li Chengda, Duke of Yuyang, and Li Chengluan, Duke of Fangshan. However, after the incident at Xuanwu Gate, Li Jiancheng and Li Yuanji's descendants were ordered to be killed by Li Shimin to ensure the stability of the throne. However, among Li Jiancheng's descendants, there was one person who might have survived. That was the great poet Li Bai. He might be Li Jiancheng's great-great-grandson.

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.

Li Jiancheng's wives were Zheng Guanyin and Yang Shi. Zheng Guanyin was Li Jiancheng's Crown Princess, and Yang Shi was Li Yuanji's wife. The other search results did not mention Li Jiancheng's other wives.

Li Jiancheng had five daughters. Among them, there was a clear record of the second daughter, Li Wanshun, who was conferred the title of Wenxi County Lord. The details of the other four daughters were not recorded.

Li Jiancheng really liked Ruoxi. In the TV series " Li Shimin, the King of Qin ", Li Jiancheng had a deep love for Princess Ruoxi, but Ruoxi liked Li Shimin. Li Jiancheng regarded Li Shimin as his greatest opponent and loved Ruo Xi deeply, but he was assassinated by Ruo Xi in the end. Therefore, it could be said that Li Jiancheng liked Ruo Xi.

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.

We can see how Li Shimin treated Li Jiancheng's concubines. Li Shimin adopted a different attitude towards Li Jiancheng's concubines after the incident at Xuanwu Gate. Li Jiancheng's Crown Princess Zheng Guanyin was moved to another residence, while Li Yuanji's Princess Yang became Li Shimin's concubine and gave birth to Prince Li Ming. Zheng Guanyin died in 676 at the age of 78. Li Shimin mourned her deeply and buried her with a grand ceremony. Yang died of illness in 647, and her posthumous title was still Princess Chao. It could be seen that Li Shimin treated Li Jiancheng's concubines differently. He respected and remembered Zheng Guanyin more, while he gave favor and special treatment to the Yang family.
