Li Chenggui was born in the private residence of Huanzu (Yongxing Palace) in Heishili, Yongxing County, North Korea's Shuofang Road (now Jing Xian Road) on October 11th, the first year of Zhiyuan. His father, Li Zichun, is the general manager of Shuangcheng in Mongolia and a family in North Korea. Li Chenggui is a young official in North Korea. He went to the Northeast Marshal to save trouble, served as a doorman and became sworn brothers with the Nuzhen leader Li Zhilan (played by Tong Dulan). 136 1 year, a South Korean family, Park Yi, rebelled. At that time, Li Chenggui, a general living in Jinwu, volunteered to lead an army of only 1500 people to defeat the rebels with Li Zhilan and save the Korean dynasty. Subsequently, Li Chenggui led the army to repel the attack of the Red Scarf Army, an anti-Yuan force in China. With his outstanding military exploits, he soon became the right-hand man of the DPRK officials. During the period from 135 1 to 1368, it was at the end of the Yuan Dynasty in China that there were many rebellions in the south of the Yangtze River. Finally, Zhu Yuanzhang put down all kinds of civil strife, and proclaimed himself emperor in Yingtian on 1368, with a clear title. At the same time, due to the unclear situation in China, pro-Yuan faction headed by Cui Ying and pro-Ming faction headed by Li Chenggui appeared in North Korea. The two factions contended, and the pro-Ming faction finally won. Li Chenggui and other new bureaucrats abolished the private land system in North Korea, and used the "elder brother's style of play" to sweep away the old forces of the Korean dynasty. This law not only gives land to Li Chenggui, but also gives it the power to rule the country. In A.D. 1380, Li Chenggui went south to Nanyuan area, where it pacified the Japanese invaders who had been harassing for many years, successfully annihilated a huge enemy force and captured more than 600 Japanese pirates. Since then, Li Chenggui's prestige and power have increased day by day. 1388, the Ming dynasty established Tieling Wei at the southern end of South Hamgyong Road (1355 was annexed by North Korea) and sent a message to North Korea. Cui Ying urged korean king and Xie Xin to venture into Liaodong. Li Chenggui was supported by Li Zhilan and strongly opposed. In April of that year, Xin Qiji invaded the Ming Dynasty. After crossing the Yalu River, Li Chenggui found it difficult to March, with low salary and low morale. So he returned to Matsui, deposed Qi Xin and exiled Cui Ying. Since then, Li Chenggui made Xinchang, the son of Shuxin, king and abolished it, and made Yao Yao the imperial clan of Korea (King Gong). On July 16th, the 25th year of Ming Hongwu (1392), Li Chenggui ascended the throne in Matsui (Kaesong) Shou Chang Palace at the initiative of North Korean Minister Li Zhilan and Zuo Shi Zhong You Kelian, Zheng and Zhao Jun, etc. He is fifty-eight years old. Li Chenggui, with the topic of "knowing the state affairs of North Korea", said that korean king had fainted and he had to be pushed to the throne. Zhu Yuanzhang said indifferently, "I respect the death of Wang, saying that he has a son, please make it, and then sayno." Yao Yao is considered a decent prince, so please set it up. He went again today. If you send people again and again, you may be king. I don't ask, teach him to do it himself, and he will also comfort the Sui people and communicate with each other. "Soon, Li Chenggui drew up two titles-"Chao "(ancient name) and" He "(Li Zichun's official land), and asked Zhu Yuanzhang to decide. Zhu Yuanzhang chose the word "North Korea", but because Li Chenggui was "stubborn and cunning", he didn't officially seal it. So Li Chenggui's title was changed to "The Right to Know about Korean Affairs". As soon as Li Chenggui acceded to the throne, he honored the four sai-jo as king and changed his name to Li Dan (hereinafter referred to as Li Chenggui for the sake of unification). In the same year 1 1 month, Li Chenggui made Hanyang its capital, and built an ancestral temple and Miyagi. At the same time, Zheng and others formulated Korean classics. In view of the influence of korean king's worship of Buddhism on state affairs, Li Chenggui pursues the national policy of worshipping Confucianism and restraining Buddhism. Most of the land in the temple was confiscated, the slaves in the noble manor were released, and policies to persuade agriculture were implemented, such as reclaiming farmland, improving farm tools and grains. In A.D. 1398, the first prince rebelled in North Korea and gave way to the second son Li. 1400, the rebellion of the Second Prince broke out and fled to Xianxing. 1402, Li Chenggui was taken back to Beijing by his son Li Fangyuan (see Xianxing's errand) and lived in Changde Palace, a detached palace. In the sixth year of Yongle in Ming Dynasty (1408), he visited another hall in Yanguang Building of Changde Palace on May 24th. A total of seven years in office, ten years in office, 74 years old in the Spring and Autumn Period. In the Ming Dynasty, it was given to Kang Xian. Buried in Jianyuan Mausoleum at the foot of Enzan Ijuin in Yangzhou, a suburb of Seoul. 500 years later, Li Xi, the descendant of Emperor Gaozong, proclaimed himself emperor, catching up with the ancestor emperor, and honored Li Chenggui as a Taizu, a straight man, a just and honorable emperor of Zhaotong, Yongming and SHEN WOO.
