The 8th year of the Emperor Gaozu (199 B.C.)
In winter, the Emperor led an attack on the remaining forces of Xin, King of Hán, at Dongyuan county, passing through Boren county. Guan Gao and other officials had assassins hide in the double wall of a latrine. The Emperor planned to stay overnight but suddenly asked, “What is the name of this county?” The reply was “Boren.” The Emperor said, “Boren sounds like po’ren, which refers to people under duress.” He then decided to leave without staying overnight. In December, the Emperor returned to the capital from Dongyuan county.
In Spring of that March, the Emperor traveled to Luoyang. He decreed that merchants were prohibited from wearing clothing made of silk, embroidery, fine brocade, thick silk, fine cotton, coarse cotton, or hempen fabrics. They were also forbidden to carry weapons or ride horses as well as carriages.
In September, during the autumn, the Emperor departed from Luoyang, accompanied by the King of Huainan, the King of Liang, the King of Zhao, and the King of Chu.
The Xiongnu leader Modu Chanyu frequently harassed the northern border of the Han dynasty. Concerned, the Emperor sought advice from Liu Jing. Liu Jing responded, “The soldiers and officers are weary from battle, and it is unwise to resort to force now. Modu gained power by killing his father and seizing his wives and consorts. He relies on brute strength, and it’s difficult to sway him with principles of kindness and righteousness. However, we can adopt a long-term strategy, allowing his descendants to become our vassals. But I fear your majesty may not be able to convince yourself to do it.”
The Emperor asked, “What should I do, then?”
Liu Jing replied, “If your majesty offers your eldest princess in marriage to him and provides generous gifts, he will admire you and view himself as your son-in-law. If a son is born by the princess, he will become the crown prince. You can gift items that the Han dynasty has in abundance but that the Xiongnu lacks, in each season year-round. You may use these opportunities to send lobbyists to educate them on Han cultural etiquette. Modu will be your son-in-law during his lifetime, and after his death, your grandson will become the new Xiongnu leader. Have you ever known a grandson daring to disrespect and contend with his grandfather? You can gradually subjugate them without warfare. If Your Majesty cannot send the Eldest Princess, but instead has members of the imperial clan or the harem falsely claim to be the princess, once they find out, they will not be willing to honor or maintain close relationships, and it will be of no benefit.”
The Emperor found the idea appealing and considered sending his eldest princess to Modu. However, Empress Lü wept day and night, saying, “I only bore the crown prince and one daughter. How can we ditch her to the Xiongnu?” The Emperor ultimately could not bear to send his daughter, and the plan fell through.
The 9th year of the Emperor Gaozu (198 B.C.)
In winter, the Emperor selected a young girl from a plebeian family, bestowed upon her the title of ‘Eldest Princess,’ and sent her to marry the Xiongnu leader. He also dispatched Liu Jing to negotiate and finalize the marriage alliance.
Sima Guang’s commentary: Marquis Jianxin’s proposal to marry off a young woman to a vallian, Modu, who cannot be swayed by benevolence and righteousness is inherently self-contradictory. The bonds of kinship and distinctions of rank can only be appreciated by those who follow the principles of benevolence and righteousness. How, then, can we expect to win over the Xiongnu through marriage?
In the past, emperors dealt with barbarian tribes either by showing them kindness or by demonstrating their might. There is no record of marriage being used as a diplomatic tool. Moreover, since the Xiongnu leader treated his own father as prey, how could he be trusted to show respect to his wife’s family? The strategy of the Marquis of Jianxin was fundamentally flawed, and how could he even consider taking away Princess Yuan of Lu, who had already been Queen of Zhao?
Liu Jing returned from the Xiongnu and reported, “The Xiongnu‘s Baiyang and Loufan kings are only 700 li from Chang’an. A light cavalry could reach Qinzhong(a.k.a. Guanzhong) in a single day and night. Qinzhong has just been pacified, with a small population and fertile land. Increasing the population would help consolidate the region. When the monarchs established in the past, only the families of Tian in Qi, and the Shao, Jing and Qu clans in Chu prospered first. Although Your Majesty now rules Guanzhong, the population is sparse. In the east, the powerful clans of the former six states remain strong. If sudden unrest occurs, Your Majesty cannot be at ease.
I recommend moving the influential clans of the former six states, along with other prominent families, to Guanzhong. Their presence will act as a deterrent to the Xiongnu, and they can be mobilized to vanquish the east if the monarchs revolt. This is the strategy of strengthening the core and weakening the periphery.”
The Emperor agreed: “A good idea!” In November, he relocated the major clans of the Shao, Qu, Jing, Huai, and Tian families, along with other powerful households, to Guanzhong. A population of over 100,000 were given fertile fields and houses there.
In December, the Emperor traveled to Luoyang.
