Emperor Wu of the Han Dynasty was born in the first year before Emperor Jing of the Han Dynasty, his mother Wang, and the middle son of Emperor Jing of the Han Dynasty. When his mother Wang was pregnant, Emperor Jing of Han was still the crown prince. Wang dreamed that the sun entered her arms, and after telling Emperor Han Jing, Emperor Han Jing said: This noble expedition is also. Before Liu Che was born, his grandfather, Emperor Wen of Han, died. After Emperor Jing of the Han Dynasty ascended the throne, Liu Che was born, and he was also the only son of the Wang family.

Liu Che was first famous, born intelligent, insightful, and free to advance and retreat. When he was three years old, Emperor Jing hugged him on his lap and asked Liu Che: Is Le the Son of Heaven? Said to him: From the sky, not from the child. I wish to live in the palace every day and tease in front of Your Majesty. Liu Yu's honest answer made Liu Qi have to look at this son differently.

Liu Yu has an amazing memory, a particularly strong desire for knowledge, and especially likes to read the deeds of ancient sages and emperors in books, and never forgets them. Emperor Jing was deeply surprised. Liu Yu has been suing the saints since Fuxi, and tens of thousands of words have been recorded in the Yin and Yang Diagnosis Dragon Diagram Turtle Book, and not a single word has been lost. At the age of seven, Emperor Jing changed Liu Yu's name to Liu Yu, and the word "thorough" means that he is full of wisdom and meets the requirements of sainthood.

Liu Che was named the king of Jiaodong as a prince. Emperor Jing's eldest son, his half-brother Liu, was named crown prince. Queen Bo, who had no children and no favors, was deposed. Liu Rong, the abolished prince of Li, was the king of Linjiang; In the summer of April, his mother Wang was made the queen, and Liu Che was made the crown prince. His becoming the crown prince had a lot to do with his mother, Empress Xiaojing, and his aunt, Princess Guantao, Liu Concubine. Liu promised to marry her daughter, Chen, to Liu Che, the then four-year-old king of Jiaodong. Liu Che later married Chen as a concubine.

Emperor Jing died, and the crown prince Liu Che was the emperor, and the empress dowager Dou was called the empress dowager, and the empress Wang was called the empress dowager.

At the beginning of the enthronement, the Han Dynasty had been established for more than 60 years, the world was stable, and the ministers of the imperial court hoped that the Son of Heaven would hold a ceremony to worship Mount Tai and Liangfu Mountain, and change and determine various systems. The emperor also admired the doctrine of Confucianism, and recruited wise men through virtuous and upright subjects. Zhao Xuan, Wang Zang and others relied on their erudition to become officials and reached the high position of the minister. They wanted to suggest that the Son of Heaven should establish a Ming Hall in the south of the city according to the ancient system, as a place for the princes of the court. The plan they drafted for the Son of Heaven to go on patrol, seal Zen and change the calendar and color system has not yet been completed, just in time for the Empress Dowager Dou is still advocating and believing in the Taoist doctrine of the Yellow Emperor and Lao Tzu, and does not like Confucianism, so they sent people to privately investigate the illegal profit-seeking and other things done by Zhao Juan and others, and summoned Zhao Juan and Wang Zang to commit suicide, and the things they proposed to set up were abolished.

It was not until the death of Empress Dowager Dou that Emperor Wu of the Han Dynasty was able to seize power. He further weakened the power of the princes and kings, issued a decree of encouragement proposed by the minister's lord's father, and used the legal system to promote the princes and kings to divide their sons into princes, so that the fiefs of the princes and kings had to shrink themselves. At the same time, he set up a history of assassination and supervised the place. Strengthen the centralization of power, organize private businesses such as iron smelting, salt boiling, and brewing under the management of the central government, and prohibit the vassal states from minting money, so that the financial power is centralized in the center. Ideologically, Dong Zhongshu's suggestion of deposing the hundred schools of thought and respecting Confucianism alone paved the way for the special status of Confucian education in ancient China, and established a special Confucian education Taixue in Chang'an, which was the highest institution of learning at that time. During the reign of Emperor Wu of the Han Dynasty, the Han Dynasty did not lack the idea of the rule of law. While propagating Confucianism, Emperor Wu of the Han Dynasty also used statutes and criminal laws to consolidate the authority of the government and demonstrate the status of imperial power.

Emperor Wu of the Han Dynasty asked Long Hui to surrender to the Han clan, Long Hui refused Emperor Wu of the Han Dynasty because he did not want to be restrained, and Emperor Wu of the Han Dynasty sent Zhou Yafu to lead 100,000 troops to conquer Longcheng, and the army attacked the Shangjun next to Longcheng, and the garrison of Shangjun was Long and commanded the First Army, the Fourth Army, the Fifth Army and the Eighth Army. Long Hui will be in charge of patrolling the dragon city of the 10,000 special gold kiri army also reinforce the upper gun. Long He and the Han army led by Zhou Yafu fought against the first battle, and the advantage was judged, most of the Han army was armed with iron ring swords, and the bronze weapons of Long Hui's soldiers were difficult to contend with. Most of the bronze halberds used by the First Army on the chariot were cut off by the ring head knife after a charge, and the remaining soldiers abandoned the chariot and resisted with copper shields and bronze battle axes, and soon the whole army was wiped out except for dozens of people who fled, and the Fourth Army fought more than 1,000 Han troops and suffered casualties. The Fifth Army faced the cavalry of the Han army, and took advantage of the numerical advantage to fight with the Han cavalry with forging rods and bronze knives, and waited until the main force of the Han army surrounded the whole army and no one escaped. The defender Long Ji also died on the battlefield, the Eighth Army saw that the main general was dead and retreated to Mayi, and the reinforced Tejin Kiri army immediately fought with the vanguard of the Han army after arriving in Shangjun until all of them were killed, and the Han army was stunned by more than 2,000 elites. The soldiers in Feixin are absolutely loyal and have no fear of death.
