When Liu Xiu proclaimed himself emperor, the world was still in turmoil. The remnants of the Red Eyebrow and Green Forest Army occupied Chang'an, the old capital of the Han Dynasty, and the Guanzhong area. Longxi and Sichuan were both occupied by separatist regimes. Liu Xiu's act

In the first year of Jianwu (AD 25), Liu Xiu rebuilt the Han Empire in Luoyang. Because the capital was east of Chang'an, Liu Xiu's Han Dynasty was called the Eastern Han Dynasty by later generations. When Liu Xiu proclaimed himself emperor, the world was still in turmoil. The remnants of the Red Eyebrow and Green Forest Army occupied Chang'an, the old capital of the Han Dynasty, and the Guanzhong area. Longxi and Sichuan were both occupied by separatist regimes. Liu Xiu's actual control areas were only Hebei and the Central Plains. area , the most important political task before Liu Xiu is to unify the world, otherwise Liu Xiu would be nothing more than a separatist warlord, and to unify, he must fight the world over again with one knife and one shot. Nonsense, who doesn't want to be the boss? Why do you want to work for Liu Xiu?

So, not long after he proclaimed himself emperor, Liu Xiu started the unification war. Maybe Liu Xiu had the halo of the protagonist, maybe his opponent was too weak. Liu Xiu's unification war went surprisingly smoothly, and Liu Xiu gathered around him. The best civil servants and generals in the world at that time, after 12 years of unification During the war, Liu Xiu defeated various separatist regimes and finally unified the world. In order to reward these old brothers who followed him to conquer the world, Liu Xiu high-profilely awarded 28 of his most trusted heroes, because most of them were military generals. They were known in history as " Yuntai Twenty-Eight will ", later generations envied it as "Yuntai Twenty-eight Stars".

Liu Xiu was one of the few founding kings who did not kill his heroes. Even after the founding of the country, he still let his heroes and generals take charge of heavy troops. Perhaps it was Liu Xiu's sincerity that earned the loyalty of the heroes. Throughout the founding eras of the dynasties, Liu Xiu's period was the most harmonious moment when the emperor and the heroes got along. The emperor treated the heroes well and the heroes were loyal to the emperor, forming a good political ecology. Without exception, these heroes and generals were all heroes of the moment. With the assistance of these people, Liu Xiu quickly pushed the reborn Han Empire to its peak, and the Eastern Han Dynasty entered the center stage of history with a new attitude. But an episode is naturally inevitable, and this episode happened thousands of miles away in Indochina.

In the 17th year of Jianwu (AD 41), Jiaozhi women Zhengbi and zhenger took advantage of Liu Xiu's opportunity to reduce the Jiaozhi County garrison to launch a rebellion and occupied the country in one fell swoop. Jiaozhi County, Jiaozhi was the most important strategic location of the Han Dynasty in the Indochina Peninsula. The fall of Jiaozhi led to the separation of the Indochina Peninsula from Lingnan. Jiuzhen, Rinan, Hepu and other places located south of Jiaozhi were blocked from the Han Dynasty The relationship was completely occupied by Zheng Fang and Zheng Er. Afterwards, Zheng Tie proclaimed himself king in Fuling and openly broke with the central court of the Han Dynasty. When news of the Zhengzi and Zhenger rebellions reached Luoyang, Liu Xiu quickly convened an emergency military meeting to discuss countermeasures. Faced with such a blatant rebellion, the Han Dynasty had no room for compromise. Countering the rebellion was the only political correctness. Just study how to counter rebellion? The specific question of who to send out? Because Jiaozhi is far away from Lingnan, thousands of miles away from Luoyang, and the natural conditions are harsh, the logistics support problem for the army's expedition is even more of a big trouble.

Just when everyone was at a loss, the 62-year-old founding general Ma Yuan took the initiative to ask for help. Liu Xiu thought that Ma Yuan was old and could not bear to let him work on the expedition and did not want Ma Yuan to take command. Ma Yuan saw Liu Xiu's doubts, and Ma Yuan said passionately, "A general cannot die of old age and return to his body wrapped in horse leather." Ma Yuan's heroic words finally convinced Liu Xiu. Immediately, Liu Xiu appointed Ma Yuan as General Fubo, Fulehou Liu Long as deputy general, and led the building general Duan Zhi to lead tens of thousands of troops to attack Jiaozhi. When the troops arrived at Hepu, Duan Zhi passed away and Ma Yuan also led the army. As a result, Ma Yuan unified his army by sea and land, marching more than a thousand miles.

In the 18th year of Jianwu (AD 42), Ma Yuan led his army to Langbo and defeated the main force of Zheng Side and Zheng Er. He beheaded thousands of people and surrendered more than 10,000 people. The forces of Zheng Side and Zheng Er suffered a heavy blow. blow. Ma Yuan took advantage of the victory to attack, but was defeated several times in the Jinxi area, and the enemies fled in all directions. In the first month of the 19th year of Jianwu (43 years), Ma Yuan beheaded Zheng Side and Zheng Er and sent their heads to Luoyang.After that, Ma Yuan personally led more than 2,000 large and small warships and more than 20,000 soldiers to conquer Duyang and other tribes of the remaining party. From futile to violent attacks, he killed more than 5,000 people and captured the entire territory of Jiaozhi. Jiuzhen, The Zhengbi troops in Rinan, Hepu and other places also surrendered. Ma Yuan completely put down the Zhengbi and Zhenger rebellions, and once again planted the Han flag over the Indo-China Peninsula.

After the war, Ma Yuan stayed in Jiaozhi for a short time, leading Han soldiers to participate in the post-war reconstruction work in the Jiaozhi area, and taught advanced farming production techniques to the local Jiaozhi people, restoring the order of production and life in Jiaozhi. With Ma Yuan's comfort, Peace returned to Cochin. Seeing that the situation was stable, Ma Yuan began to prepare his troops to return to Luoyang. He also erected bronze pillars there to show his merits. He believed that the Han boundary was the extreme point. There were four places: one in the west of Qinzhou as the east boundary; one in the south boundary of Pingxiangzhou; The north of Linyi is bounded by the sea; the south of Linyi is bounded by mountains. Engraved on the copper pillar: "When the copper pillar breaks, Jiaozhi will be destroyed." After returning to Luoyang, Liu Xiu granted Ma Yuan the title of Marquis of Xinxi and granted him a household of 3,000 households.

As an aside, General Ma Yuan, the fighting hero who safeguarded the territorial integrity of the Han Empire, is not very well-known today, but he has a descendant who is really a household name, and that is , one of the Five Tiger Generals of the Shu Han Dynasty during the Three Kingdoms period. Ma Chao Ma Mengqi, in the end, the son of a dragon and a phoenix is ​​born, and the son of a mouse can dig holes.
