At the end of the Qin Dynasty, a peasant uprising broke out in Chen Sheng and Guangwu. All the princes in the world are against Qin. The Central Plains was plunged into war. At this time, Nanhai county magistrate Ren Tao was seriously ill. On his deathbed, he entrusted the military and political power in the South China Sea to Longchuan Zhao Tuo. Zhao Tuo, following the legacy of Ren Tao, sent troops to conquer the whole Lingnan area because the Qin government had no choice, and the Central Plains was uneasy. It blocked the South China Sea and took a mountain risk, blocking the peasant uprising in the Central Plains. Set up South Vietnam, separate yourself from the south and sit and watch the world.
During the reign of Zhao Tuo, Chinese culture was widely spread in Lingnan. Chinese characters spread all over the country, introduced the production technology and inventions of the Central Plains, and started the development and progress of agriculture and economy in Lingnan area. People live and work in peace and contentment, and social development has entered a new period of development, thus making Lingnan region integrate into Chinese civilization.
In 202 BC, Emperor Gaozu Liu Bang established the Western Han Dynasty, and the history of China entered the second unification. Facing the separatist regime of South Vietnam, Emperor Gaozu Liu Bang adopted the strategy of "planning slowly", and first admitted that Zhao Tuo had the right to be the king of Nanhai, Guilin and Elephant in the three counties of Lingnan. In exchange for Zhao Tuo's submission, Zhao Tuo accepted the knighthood of the Central Committee of the Han Dynasty, calling himself the King of South Vietnam, and South Vietnam became a vassal state of the Han Dynasty.
Since then, all the kings of South Vietnam have surrendered to the Han Dynasty and obeyed the central authorities. History rolled forward, and by the time South Vietnam mourned the king, the Han Dynasty had begun to control the appointment of officials in South Vietnam. South Vietnam is also divided into internal and independent factions. Lu Jia, a powerful minister, staged a coup and seized the regime of South Vietnam. Finally triggered the Han Dynasty to send troops to intervene. Liu Che, the Emperor of the Han Dynasty, decided to annex South Vietnam, and sent general Lü bode to lead a hundred thousand troops. In 65438 BC+065438 BC+02 BC, Nanyue State perished and returned to Chinese territory.
The establishment of Nanyue State is a separatist force formed by Zhao Tuo's personal prestige and military talent. The collapse and chaos of external factors in Qin Dynasty drove Zhao Tuo's ambition to establish Nanyue State in Lingnan. It is precisely because of the establishment of Nanyue State in Zhao Tuo that Chinese Han civilization can be implanted into Lingnan area, thus making this territory always under the influence and control of Han civilization. In the end, Lingnan did not become an enclave, but became the inheritor and disseminator of Han civilization and culture.
