Although Emperor Liu Ying was not very good at managing affairs, with Empress Lu sitting in the palace and Cao Shen and other experienced and high-level ministers in the imperial court, the political situation formed a delicate balance, and the state apparatus of the Han Dynasty still maintained a healthy operation.

In the autumn of 194 BC, Lu Xuan, who was stranded in the Xiongnu, died. Lu Juan was not very reluctant to surrender to the Xiongnu, and he secretly befriended the Xiongnu just to take advantage of the situation to keep the position of the princes and kings. Lu Juan did not expect that Liu Bang decisively ordered Fan Hao to lead 200,000 troops to quell the rebellion. Seeing that Liu Bang was really moving, Lu Juan fled in time with thousands of family members and cronies. Only, where can you escape? Do you really want to be a Hun?

After all, Lu Juan grew up with Liu Bang, and his affection is extraordinary. He took thousands of people to set up tents by the Great Wall and stayed, wanting to wait for Liu Bang to recover from his illness, so he personally went to Chang'an to plead with Liu Bang in person. If he really wants to do this, Liu Bang will definitely pardon him, and the princes and kings will not be able to do it, it is better than going to the Xiongnu to send people to the fence. What Lu Juan was waiting for was the news of Liu Bang's death. He had no confidence in Empress Lu, and after thinking about it, he could only defect to the Xiongnu.

Mao Dunshan became the king of Donghulu in Feng Luxuan. Lu Xuan, the king who surrendered, did not approve of it, and the generals of the Huns dared to bully him, and often came to him to fight the autumn breeze and go along with something. Lu Juan often regretted it and wanted to return to Dahan. People, sometimes one wrong step is the wrong step. Depression naturally did not make his health better, and he died of illness after more than a year of being in the Huns.

Mao Dunshan heard that Liu Bang had passed away and was very concerned. This steppe pride has his eyes on the huge country of the south. A lot of things happened in the next two years, and Mao Dun gradually learned about the current power relationship of the Han Dynasty and decided that Empress Lu was in charge. He planned to flirt with Empress Lu, which was both a provocation and a temptation.

Mao Dunshan Yu wrote an explicit letter to Empress Lü, which said: I am a lonely and lonely monarch, growing up in the wilderness and grassland, I have come to the border many times, and I want to visit the Central Plains. Your Majesty is widowed, and I am single, neither of us is happy. I am willing to do everything I can so that you will no longer lack joy. (May all have for nothing)

Empress Lu was a strong woman, and after reading this unobtrusive letter, she was furious and summoned the minister of civil and military affairs to kill the envoy and send troops to attack the Xiongnu.

When the fierce man Fan Hao heard that his sister-in-law was molested, he was very annoyed, and roared angrily: "I am willing to lead 100,000 troops to sweep the Huns!" ”

The ministers took care of Empress Lu's emotions and said that the Xiongnu should be fought.

Only Zhonglang stood up against Ji Bu. Ji Bu is righteous, keeps his promises, and is trustworthy. The idiom 'a promise of a thousand gold' is about him. Ji Bu was blunt and said, "Fan can be killed." When Emperor Gaozu led an army of 400,000 and was still besieged in Baishan Mountain, how could Fan Hao sweep the Xiongnu with only 100,000 horses? It's lying to your face. The Hun barbarians were like beasts, and there was no need to be happy or angry at their words. ”

After all, Lu Hou was a mature politician, she calmed down and praised Ji Bu again and again for being right.

Empress Lu sent a diplomat to send a reply letter to Mao Dun Shan Yu, which said: I am very frightened to receive your greetings. I thought about it carefully, I am old and frail, my hair has fallen out, my teeth are loose, and I can't walk steadily, so why should you insult yourself so much! It is better for our two countries to live in peace. Two carts and eight horses will be sent to you.

Empress Lu's reply was clearly belittling herself, but in fact she was belittling Mao Dun, not tearing her face, and sending carriages and horses to appease. Mao Dun got the reply and felt that Lu Houmian was a character, and he gave back a few horses from the Han Dynasty and wrote: I don't know the customs and etiquette of the Central Plains, but fortunately, Your Majesty tolerated me.

After this contest, the Han and Xiongnu reached a consensus: continue to maintain the stability of bilateral relations. In the spring of 192 BC, the Han Dynasty selected another girl from the clan to be named a princess and marry Mao Dunshan Yu.
