The reason why Li Jinglong became a mole could be explained from the following aspects. First of all, Qin Wangfei told Li Jinglong that they not only wanted to gather intelligence, but also wanted to drive a wedge between the Zhu family's father and son, and the relationship between the monarch and his subjects, so as to plant the hidden danger of the dynasty collapsing. Hai Bie thought that Li Jinglong was a man who liked to be extravagant and self-righteous, and was easily deceived. Secondly, on the way to escort Princess Haibie, Li Jinglong was full of praise for Haibie's beauty and did not refuse her requests, showing that he liked Haibie and fell in love with her. Hai Bie recommended Li Jinglong because he had a good impression of her and could use him to achieve his own goals. In addition, Li Jinglong was at odds with Zhu Di during the Battle of Jingnan. The more he went, the more he leaned towards Zhu Di. In the end, he opened the door and surrendered, becoming Zhu Di's great hero. These clues indicated that Li Jinglong might be a mole planted by Zhu Di beside Emperor Jianwen. However, the specific details and motives of Li Jinglong becoming a mole were still unclear, and further research and understanding were needed.
Li Jinglong's ending was not ideal. After Zhu Di entered the city, Li Jinglong was placed under house arrest and stripped of his title and property. He could not leave his home for the rest of his life until he died of depression at the end of Yongle. Therefore, it could be said that Li Jinglong did not have a good ending.
There was no clear record of Li Jinglong's cause of death. Some documents believe that he died in the fourth year of Ming Xuande (1429), while others record that he died in the last years of Yongle. Li Jinglong's descendants were conferred the title of Marquis of Linhuai during the Qing Dynasty and had been officials for generations. However, the search results did not provide any conclusive information about his specific cause of death and outcome. Therefore, it was impossible to accurately answer the cause of Li Jinglong's death.
Zhu Di successfully defeated Li Jinglong through ingenious strategies and military plans. During the Battle of Jingnan, Zhu Di led the army to sweep the outer areas of Beiping and handed the city defense work to his eldest son, Zhu Gaochi. Li Jinglong took advantage of Zhu Di's absence and launched a fierce attack on Beiping City. Although Beiping City was strong, Li Jinglong believed that Zhu Gaochi would not be able to resist his army, so he decided to take the city in one go. However, Zhu Di was already prepared. He had sent Ping An and the others to set up an ambush in advance, taking advantage of Li Jinglong's attack to launch an attack, causing Li Jinglong's army to lose. Zhu Di's strategy successfully distracted Li Jinglong, making him unable to deal with Zhu Di's main force at the same time. This eventually led to Li Jinglong's army suffering heavy losses, and Zhu Di successfully defeated him.
Li Jinglong was the son of Li Wenzhong, the founding general of the Ming Dynasty. Li Wenzhong was Zhu Yuanzhang's nephew and was ranked third on the list of meritorious officials. Therefore, Li Jinglong was Zhu Di's nephew, and Zhu Di was Li Jinglong's uncle. Their relationship could be called uncle and nephew.
Li Jinglong's son was Li Jingtai. Li Jingtai was Li Jinglong's eldest son. He became an important general in the Ming Dynasty. As for whether Li Jinglong had other sons, the search results did not mention any relevant information, so it was impossible to confirm.
Li Jinglong's father was the founding general of the Ming Dynasty, Li Wenzhong.
Li Jinglong's descendant was Li Zongcheng. Li Zongcheng was Li Jinglong's great-grandson. He had inherited Li Wenzhong's family background and served as the commander of the Nanjing Jinyiwei during the Ming Dynasty. When Li Zongcheng was invaded by the Japanese pirates, the Ming Dynasty sent troops to support him. After several battles, the two sides decided to reconcile. The records of Li Jinglong's son and other descendants were not detailed. They only knew that Li Jinglong's great-grandson, Li Xuan, was appointed by the imperial court as the commander of the Nanjing Brocade Guard.
Li Jinglong's performance in the war was not outstanding. He had been defeated many times and was even more arrogant and ignorant than Zhao Kuo. Although he was the son of a general, he did not understand military affairs. He did not know how to lead troops, nor did he know how to fight. However, his background and family background made him important. His father was Li Wenzhong, the general of the early Ming Dynasty, his mother was Zhu Yuanzhang's sister, and he himself was Zhu Yuanzhang's nephew. Li Jinglong inherited his father's title and was put in an important position during Zhu Yunwen's time. However, he did not perform well in the war with Zhu Di and eventually retreated and surrendered. Therefore, according to the information provided, Li Jinglong did not perform well in the war.
There was no clear answer to the question of whether Li Jinglong had gone easy on them during the Battle of Jingnan. Some documents mentioned that Li Jinglong might have gone easy in the battle to ensure Zhu Di's victory, but there were other views that Li Jinglong's victory was a manifestation of his military talent. However, these opinions did not provide enough evidence to support or refute Li Jinglong's claim that he had gone easy on her. Therefore, it was impossible to determine if Li Jinglong had gone easy on them.
