There was some controversy and uncertainty about Li Chengqian's leg disease. There was a saying that Li Chengqian's leg disease might be caused by hereditary or congenital diseases, because his father, Emperor Taizong of the Tang Dynasty, Li Shimin, also had leg disease. However, another theory was that Li Chengqian's leg disease might have been acquired from an illness and might be related to diabetes. Although there were many theories about Li Chengqian's leg disease, there was no conclusion that most people could agree with. Therefore, the specific cause of Li Chengqian's leg disease was still unclear.
The reason for Li Chengqian's leg disability was not clearly recorded in the history books. There were many related theories, but there was no conclusion that most people agreed with. Modern medical research showed that there were two main causes of human limb disability: permanent limb damage caused by external factors and body tissue damage caused by internal diseases. According to historical records, before the 13th year of Zhenguan (639), there was no record of Li Chengqian being seriously injured by an accident (such as falling off a horse, assassination, etc.). Therefore, it was impossible to determine whether Li Chengqian's disability was caused by external factors or internal diseases. As for the specific reason for Li Chengqian's leg disability, there was no conclusive answer yet.
Li Chengqian was the eldest son of Emperor Taizong of the Tang Dynasty and was originally the heir to the crown prince. However, he broke his leg when he was young, causing him to be disabled. This physical disability caused him to lose the qualifications to be the Crown Prince. As for the specific reason for his broken leg, the search results did not provide exact information. Therefore, regarding the details of Li Chengqian's broken leg, I can't provide an answer at the moment.
There was no specific information about the specific reason for Li Chengqian's broken leg. The history books did not clearly record the cause of his leg disability. According to modern medical research, there were two main causes of human limb disability: permanent limb damage caused by external factors and body tissue damage caused by internal diseases. However, the cause of Li Chengqian's disability was not clearly recorded. There was a speculation that his foot disease might have occurred during the period of serious illness in the fifth and seventh years of Zhenguan, but this speculation was not recorded in detail in historical materials. Therefore, the details of Li Chengqian's broken leg could not be provided at present.
Li Shimin liked Li Chengqian. Li Shiming was very fond of Li Chengqian and had made him the Crown Prince from a young age. He had invited many great teachers to teach him and spared no effort in nurturing him, placing the future of the Great Tang on his shoulders. Li Chengqian was also very outstanding in his early years and was deeply loved by Li Shimin. Li Shimin attached great importance to Li Chengqian's education and sent Confucian masters Kong Yingda, Lu Deming, and others to teach him Confucian classics. Li Chengqian performed well in government affairs and handled state affairs in an orderly manner. He was trusted and loved by Li Shimin. However, as he grew older, Li Chengqian suffered from foot disease and became disheartened. He began to rebel and was eventually deposed as a commoner. Thus, although Li Shi Min liked Li Chengqian, due to some reasons, he eventually abolished Li Chengqian's position as Crown Prince.
Li Chengqian had the ability to govern the country. Li Shiming had high expectations for Li Chengqian and provided him with many assistance and guidance. Li Chengqian had shown his talent in governing the country, and his plans were considered valuable. In addition, Li Chengqian was also praised as " quite knowledgeable " and " quite able to judge," showing his intelligence in handling government affairs. However, although Li Chengqian had the ability to govern the country, his lifestyle gradually became absurd and decadent, which caused Li Shimin to have the idea of deposing him. Thus, although Li Chengqian had the ability to govern the country, he did not become the Crown Prince in the end.
Some records indicated that Li Chengqian might not have any descendants. According to historical records, Li Chengqian was placed under house arrest in the palace after his position as Crown Prince was abolished. There was no record of him having any children. However, there were also some records that showed that Li Chengqian left behind two sons, one of whom was called Li Xiang. However, these records did not provide detailed information about Li Chengqian's descendants. Therefore, it was impossible to determine if Li Chengqian had any descendants.
Li Chengqian has descendants. He had three sons, Li Xiang, Li Meng, and Li Jue. Among them, Li Xiang became the prime minister of Emperor Xuanzong of Tang Dynasty. The search results did not provide any relevant information on how his descendants were doing, so it was impossible to know.
Li Chengqian had a certain ability to govern the country. Emperor Taizong of the Tang Dynasty, Li Shimin, had high hopes for Li Chengqian and specially selected many people to assist and teach him. He also personally inspected Li Chengqian's governance strategy. Li Chengqian had displayed outstanding talent during his time as the crown prince. He had written three pages of governing strategies, and the content was considered very valuable. In addition, he also showed his love for learning and asked Lu Deming, a Confucian master, to teach him. He also took great pains to lead him back to the right path. These signs showed that Li Chengqian indeed had a certain ability to govern the country. However, due to the limited search results provided, it was impossible to draw a more specific conclusion.
There was no clear answer to the question of whether Li Chengqian had descendants. Some records indicate that he may not have any descendants, because after he was deposed as Crown Prince, he was placed under house arrest in the palace. There is no record of him having any children. However, there were also some records that showed that he left behind two sons, one of whom was called Li Xiang. There were also other records that mentioned that he had three sons, Li Xiang, Li Meng, and Li Jue.

Li Chengqian had three sons. The first son, Li Xiang, served as the governor of Huaizhou during Li Zhi's reign after Li Chengqian's death. He was later granted the title of Governor of Yuezhou and Duke of Huan until his death in 702. The second son, Li Jue, was Li Shimin's grandson. After he was born in the 12th year of Zhenguan, he was given a sword as a reward. As for the details of his third son, there was no mention of it.
