Who did Qin Shihuang send to guard South China?

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 and stationed troops. Another 300,000 Qin Jun went to Guangxi to fight the local Vietnamese. Although they killed Yi, the leader of the Ou tribe, their three-year campaign failed, 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.

Immediately, the Qin Dynasty set up 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 administered 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.
