Zhao Tuo, a general of the Qin Dynasty, became the first emperor of China to rule Vietnam.

In 2 1 1 year, Qin Shihuang divided Qi, Chu, Yan, Wei, Zhao and Han, and established the first centralized feudal dynasty in the ancient history of China. However, Qin Shihuang was not complacent about the new Qin Dynasty. On the one hand, he built the Great Wall in the north and assigned Meng Tian to station 300,000 troops along the Great Wall. On the other hand, Qin Shihuang enlisted 500,000 troops to conquer the land of Baiyue in the south that has not yet surrendered.

From 2 19 to 2 14, under the command of two generals from Qin Jun, Tu Sui and Zhao Tuo, the Daqin Empire finally settled the Lingnan area. However, in this process, Tu Youyou was also killed on the battlefield. Therefore, Qin Shihuang appointed Ren Tao as the coach of this Qin army. After Guilin County, Nanhai County and Xiang Jun County were formally established, Zhao Tuo was appointed as Longchuan County Order of Nanhai County by Qin Shihuang. Of course, although the official position is not high, Zhao Tuo is serious and responsible. After the implementation of the ethnic policy of "harmony but difference, taking a hundred steps", 500,000 people moved from the Central Plains to Lingnan area, and the political, economic and cultural level of this area also rose to a new level.

In 208 BC, Ren Xiao, the prefect of Nanhai County, was seriously ill. On his deathbed, Zhao Tuo, who will be well-governed, shouted to him, and Ren Tao emphasized that Nanhai County is an important treasure trove of geomantic omen. If the Central Plains Dynasty falls, Nanhai County can rely on its own geographical position to stand on its own feet. Therefore, Nanhai County Commandant issued a power of attorney to Zhao Tuo, formally handing over the military and political power in this area to Zhao Tuo. After Ren Tao's death, Zhao Tuo, who had mastered Qin Jun, immediately led troops to annex Guilin County and Xiang Jun County, and placed a large number of cronies, thus actually controlling the Lingnan area.

Then, after the death of Qin Shihuang, Qin Ershi, Hu Hai and Zhao Gao, who succeeded to the throne, ran amok, which eventually triggered the Guangwu peasant uprising, Chen Sheng. The huge Daqin Empire was finally overthrown by Xiang Yu, Liu Bang and others. Generally speaking, from the end of Qin Dynasty to the dispute between Chu and Han, the whole Central Plains region was plunged into war. In order to prevent the war in the north from spreading to the south, Zhao Tuo began to strengthen the control and blockade of Lingnan Pass. And built three lines of defense to defend Panyu. In this situation, Zhao Tuo, armed to the teeth and in control of its territory, established the Nanyue Kingdom shortly after the end of the Qin Dynasty, known as the "King of Nanyue" or "Emperor of Nanyue" in history, with Panyu as its capital, which is today's Guangzhou.

Finally, Zhao Tuo was the first king and emperor of South Vietnam, who reigned from 203 BC to 137 BC. During the period of Zhao Tuo's administration, the policy of "harmonizing and compiling hundreds of Vietnamese" promoted the integration of Han and Vietnamese nationalities, brought the advanced culture of the Central Plains to the land of South Vietnam, made South Vietnam develop better, and extended its ruling area to the northern part of Vietnam today. The emperor who ruled Vietnam and other regions was born around 240 BC and died in 137 BC. He not only became emperor in 7 1 year, but also became a man with a long life in 103.
