2. After Qin Shihuang unified the six countries, he began to advance to the land of Lingnan Baiyue. In the first year of Emperor Gaozu (206 BC), Ren Tao died of illness. Zhao Tuo conveyed the instructions to the troops at the passes in Nanling, and took the opportunity to kill the officials who were placed in Nanhai County by the Qin Dynasty and changed into his cronies. After the demise of the Qin Dynasty, in the third year of Emperor Gaozu (204 BC), Zhao Tuo rose up, annexed Guilin County and Xiang Jun County, and established Nanyue State in Lingnan, which was known as the "King of Nanyue" in history. In the summer of the 11th year of Emperor Gaozu (BC 196), Liu Bang sent doctor Lv Jia to South Vietnam to persuade Zhao Tuo to return to Han. Under the persuasion of Lu Jia, Zhao Tuo accepted the seal of Nanyue King given by Emperor Gaozu, surrendered to the Han Dynasty and became a vassal state of the Han Dynasty.
3. Zhao Tuo, king of South Vietnam, died in the fourth year of Jianyuan (BC 137) at the age of 100, and was buried in Panyu (present-day Guangzhou). After Zhao Tuo's death, his descendants continued to serve as the king of Nanyue for four generations, until11years ago, Nanyue was destroyed by the Han Dynasty. Zhao Tuo served as the deputy commander-in-chief of Qin Shihuang's 500,000 troops who attacked South Vietnam from the 28th year of the first emperor (2 19) until his death in the 4th year of Jianyuan (2 137), and ruled Lingnan for 8 1 year.
After Qin Shihuang unified the six countries, he began to pacify the land of Baiyue in Lingnan area. In the 28th year of the first emperor (2 19 BC), Qin Shihuang appointed Tu Sui as the general and Zhao Tuo as the lieutenant, and led 500,000 troops to pacify Lingnan. "One army blocked Chengling (now Yuechengling area), one army kept the plug of nine doubts (now Jiuyi Mountain area), one army was stationed in Panyu (now Guangzhou), and one army kept the border of Ye Nan. 500,000 Qin Jun is divided into five roads, with an average of100,000 roads. Among them, the "water left by one army" has nothing to do with Lingnan area, so it can be seen that only 400,000 Qin Jun crossed Lingnan area.
At the beginning of the Southern Expedition, the Qin people occupied the Guangdong area around Panyu, leaving the troops stationed. Another 300,000 Qin Jun went west to Guangxi to fight the local Vietnamese. Although they killed Yi, the leader of the Ou tribe, they failed in the three-year battle, and even the main commander Tu Sui was killed in the war. There are few historical records of the Baiyue War in the Qin Dynasty, only a few in Huainanzi, because South Vietnam blocked its connection with the Central Plains after the rebellion at the end of the Qin Dynasty.
6. Immediately, the Qin Dynasty established Nanhai County in Panyu (now Guangzhou), with Ren Tao as the county magistrate, in charge of the politics, military affairs and supervision of a county, and governed Panyu, Longchuan, Boluo and Sihui counties. Longchuan's geographical position and military value are extremely important, so Zhao Tuo was appointed as Longchuan county magistrate. Zhao Tuo built a city in Longchuan. Zhao Tuo devoted himself to stopping Vietnamese resistance and trying to appease local people. He advised soldiers to raise children in the local area and publicize the Central Plains (in a narrow sense, the Central Plains refers to today's Henan area; The Central Plains in a broad sense refers to the middle and lower reaches of the Yellow River. He also wrote to the emperor, demanding that the Central Plains residents be repatriated and moved to South Vietnam to spread the Central Plains culture.
