Which one is more important, Lingnan or the Qin Dynasty? Why did Ren Xiao and Zhao Tuo reject King Qin?

Whether Ren Xiao and Zhao Tuo return to the army to teach King Qin is not based on whether Lingnan is more important or Daqin is more important, but on whether they have the ability to turn the tide. In fact, they couldn't come back, and they couldn't be saved when they came back, so they chose to establish a country in South Vietnam and separatist rule.

1. The mountains are far away and there is no time to rescue.

Beginning in 219 BC, Qin Shihuang sent Tu Sui to lead an army of 500,000 people south to attack the land of Baiyue. By 214 BC In 1989, Ren Xiao and Zhao Tuo pacified Lingnan, and it took them five years. The army fought from the Yellow River Basin to the Pearl River Basin, a distance of three to four thousand miles. The mountainous roads in the south are incomparable to highways like the Qinchi Road in the north. If the southern expedition troops want to come back, including the time to prepare logistics and food, the time to mobilize men and horses, and the time to march, it will take at least half a year to return to the Central Plains. Taking into account the harassment suffered by barbarian tribes along the way, I am afraid that the Qin Dynasty will no longer exist after returning.

In fact, this is also the case. The uprising armies of Chen Sheng and Wu Guang were suppressed within a few months. What really put the Qin Dynasty at risk was the restoration movement of the nobles of the six countries. Even if the Qin army in South Vietnam received the news in 208 BC, Xianyang no longer belonged to Qin a year later. Therefore, Ren Qi and Zhao Tuo must have seriously thought about this issue.

2. There were not many soldiers loyal to the Qin Dynasty in the South Vietnam Qin Army

After Qin Shihuang unified the world, he organized the armies of the six countries into the Qin Army. At the same time, in order to prevent them from causing rebellion, a large part of them were incorporated into the Qin Army in the Southern Expedition. Therefore, the Qin Army in South Vietnam accounted for the majority of the original troops of the Six Nations. The loyalty of these people to the Qin Dynasty is not high, and when the Qin Dynasty is facing disintegration, if they are allowed to return to the Central Plains to work for the Qin Dynasty, they will inevitably encounter resistance from the grassroots soldiers. The most terrible thing about the chaos in the north is the rebellion of the former nobles of the Six Kingdoms. The South Vietnamese Qin Army, mainly composed of soldiers from the Six Kingdoms, can easily be instigated to rebel after returning to the north. At that time, it will no longer be a rescue, but will become a gravedigger for the Qin Dynasty. people. Ren Xiao and Zhao Tuo were unwilling to take this risk.

3. The Qin army's foundation in South Vietnam is not stable. Returning to Qinwang is equivalent to giving up South Vietnam.

At that time, Tu Sui's army went south, and the battle was extremely difficult, and it also encountered fierce resistance from the southern tribes. Due to the mountains, forests, swamps and hot and humid climate in the south, there were very heavy casualties in today's first southern expedition. Even the general Tu Sui himself was killed. Therefore, it was not easy for Ren Xiao and Zhao Tuo to conquer South Vietnam. During their rule, local tribes rebelled and robbed and killed officials many times. The immigrants who went south from the Central Plains have not integrated with the local tribes. If the Qin army withdraws at this time, it will be equivalent to giving back the land of South Vietnam that they have worked so hard to conquer. Going back may not necessarily save the Qin Dynasty, but it will also lose the south and face enemies from both sides. It is a narrow escape.

4. Qin II had long lost control of the Qin army in South Vietnam

When Ren Xiao and Zhao Tuo were conquering Baiyue in the south, Qin Shihuang was still alive, so they had no problem being loyal to Qin Shihuang. . After the death of Qin Shihuang, Prince Fusu was sentenced to death, Hu Hai ascended the throne, and Zhao Gao took over the government. This court was no longer the court during the First Emperor's time. Based on Hu Hai's calling ability, it is still unknown whether the South Vietnamese Qin Army will respond.
