In the former anti-Lu Alliance, Chen Ping and Zhou Bo of the Hero Group passed away one after another; Liu Xiang, the king of Qi of the Qi royal lineage, was depressed because he missed the throne and died a year before Chen Ping.

Two years later, Liu Zhang, the king of Chengyang, died of illness at the age of twenty-four. Crown Prince Liu Xi inherited the title.

The eldest brother Liu Xiang and the second brother Liu Zhang died in depression one after another, and Liu Xingju, the king of Jibei, was furious. He originally wanted to be the king of Liang, but he didn't succeed, and he resented Liu Heng for not giving him a fief, so he cut off Jibei County from the territory of the king of Qi and sent himself.

In May 177 B.C., King Youxian of the Xiongnu marched southward, invaded Henan (Inner Mongolia Yikezhao League area), attacked Shangjun (Suide, Shaanxi), burned and looted along the road, and threatened the capital Chang'an.

Liu Heng personally led the generals to Ganquan Palace (northwest of Chunhua, Shaanxi), set up the former enemy headquarters, and urgently ordered the prime minister to lead 80,000 troops to meet the Xiongnu.

The right virtuous king of the Xiongnu saw that the army of the Han Dynasty was coming and withdrew from the outside of the Saiwai. The Han and Hungarian sides never formally fought each other, but this use of troops was the first large-scale military operation of the Han against the Xiongnu after the siege of Baideng.

Hearing that Liu Heng went north to fight the Huns, Liu Xingju felt that the opportunity had come, he didn't want to be sullen anymore, and he was determined to give it a go and set a precedent for the kingdom to rebel against the central government.

Looking at the direction of Chang'an, Liu Xingju muttered, "Fourth uncle, didn't you let me be the king of Liang?" Now, I'm going to grab it all over the world! ”

Liu Xingju's courage is admirable. His Jibei country is also a county, there is no foreign aid, even his two nephews Liu Ze, the king of Qi, and Liu Xi, the king of Chengyang, did not follow the mix, and he didn't hear of any decent military generals inside, so he dared to rebel! Young people are angry, not so much rebellion, but rather vindictiveness and temperament.

Liu Heng was on his way back to Chang'an, when he received the news of the rebellion of the King of Jibei, although he was angry, he was not panicked, "This kid is too restless!" ”

Liu Heng methodically deployed counterinsurgency work:

1. Let the prime minister gather the 80,000 troops who went north, return to Chang'an, and defend the capital;

2. Appoint Chai Wu, Marquis of Jianpu, as the general, and govern the four-way counterinsurgency army, with a total of 100,000 troops, and rush to the northern country of Jibei;

3. Appointed Marquis Qihou Zhanghe as a general, stationed in the important military town of Xingyang, and monitored the movements of Liu Xingju's rebel group.

After the three-way people were dispatched, Liu Heng breathed a long sigh of relief, and he had a bottom in his heart about suppressing Liu Xingju's rebellion.

Needless to say, Chai Wu and Zhan He are also old revolutionaries, who participated in the anti-Qin uprising and the Chu-Han War, and their qualifications and abilities are not ordinary.

In July, Liu Heng returned to Chang'an and issued an edict to the world:

1. Liu Xingju, the king of Jibei, betrayed morality and rebelled;

2. When the imperial army has not arrived, the soldiers who lay down their arms and surrendered, the people who surrendered, and the officials who led their subordinates to surrender to defend the land and surrender are not held accountable, and their original positions may be retained;

3. Even if they participated in Liu Xingju's rebellion and are willing to repent, they will not be held responsible.

Liu Heng is worthy of being Liu Bang's good son, inheriting Liu Bang's mantle, Liu Bang's habitual united front strategy, and his skillfulness: disintegrating the enemy from the inside, tearing the other party apart, and making the enemy lose the basis for existence.

Under the onslaught of Chai Wu's army and Liu Heng's powerful tactics of attacking the heart, Liu Xingju's rebel group was defeated. In August, Liu Xingju was captured and died by suicide.

The first evil has been removed, and the threat is never asked. For those who followed Liu Xingju's rebellion, Liu Heng pardoned them. The Kingdom of Jibei was abolished and incorporated into the central government.

The invasion of the Xiongnu and the rebellion of the king of Jibei, Liu Heng showed himself in front of the world. The Son of Heaven on the throne is not only a humble and gentle gentleman, but also a brave, calm and strategic monarch in the face of strong enemies.

Emperor Liu Heng's position is even more stable!
