In the winter of 158 BC, the military minister Shan Yu led 60,000 Hun cavalry south. The Xiongnu army was divided into two routes, one to invade Shangjun and the other to Yunzhong County.

The Han Dynasty reacted quickly, and in order to defend the capital Chang'an, it deployed three armies along Weishui: Hanoi County guarded Zhou Yafu and garrisoned Xiliuyuan in the northwest of Chang'an City; Zhu Zihou Xu Li garrisoned the Thorn Gate in the north of Chang'an City; Zongzheng Liu Li garrisoned Bashang.

In order to resist the 30,000 Hun cavalry who entered Yunzhong County, Liu Heng appointed Zhong Dafu Lingfu as the general of the chariot cavalry, and garrisoned Feihu Pass (north of Laiyuan County, Hebei); Su means general, garrison sentence note mountain (west of Dai County, Shanxi).

In order to block the 30,000 Hun cavalry invading Shangjun, the general Zhang Wutun was appointed to the north (Qingyang, Gansu).

All the mobile troops that could be mobilized in the Han Dynasty were sent out!

In order to boost morale, Liu Heng personally came to the barracks to offer condolences to the three-way army defending Chang'an City.

In this inspection at the grassroots level, Liu Heng discovered a rare general - Zhou Yafu.

Liu Heng's itinerary is like this, along Weishui, from east to west, first to Bashang, then to Jianmen, and finally to Xiliuying.

Liu Heng and his entourage came to Bashang and Jianmen first, and there was no need to report these two places, and when they saw the emperor's chariot and horse coming, the sentry took the initiative to let them go.

Liu Li and Xu Li, the main generals of the two places, did not know the news until the emperor entered the camp, and came out in a panic to greet them. When the soldiers saw the emperor coming, they came out to watch in an uproar, as lively as a festival. When Liu Heng left, the lord would take all the soldiers to see off and send the emperor to the gate of the camp.

The emperor's condolence group came to the fine willow camp, and the situation was completely different. The guard of honor who opened the road in front of him was stopped outside the military gate, and the guard of honor shouted: "The emperor is coming!" ”

The captain of the gate replied: "The army only listens to the general's orders, not the emperor's edicts!" ”

When Liu Heng arrived, he sent an envoy to report with the emperor's talisman, and the main general Zhou Yafu ordered to open the military gate to greet him.

As soon as Liu Heng and his entourage entered the military gate, the soldiers guarding the gate ran forward and solemnly informed the emperor's carriage driver: "The general has an order, no carriages and horses are allowed to gallop in the military camp!" ”

The driver had to tighten the reins and not dare to let the horse run too fast.

When he arrived at the big tent of the Chinese army, Zhou Yafu was dressed in military uniform, standing outside the door to greet him, and when he saw Liu Heng, he bowed and said loudly: "I am in military affairs, and it is inconvenient to bow down, please allow me to greet Your Majesty with a military salute." ”

Liu Heng listened to it and was very moved, this is the real general! He leaned down, held on to the beam in front of the car, and saluted the soldiers.

On the way back after the end of the condolences, Liu Heng sighed to the entourage: "This is called leading soldiers!" In comparison, the management of the armies of Bashang and Thorn Gate is like child's play. If the enemy comes to sneak attack, how can you win! Zhou Yafu's army, the enemy doesn't even have a chance to sneak attack! ”

The Han Dynasty set up a position, and the Hun cavalry only lingered on the border line, not daring to go deeper. A month later, Liu Heng couldn't sit still, and he ordered the troops to take the initiative to attack. When the Xiongnu army saw the Han Dynasty army coming, they once again showed their true colors as bandits, packed up the looted supplies, and ran away.

Liu Heng was helpless, since he ascended the throne, the Huns have come to harass him on a large scale three times, and every time I advance and retreat, I chase him and run, and the Han has suffered heavy losses every time.

The Xiongnu problem must be solved! I can't solve it in my lifetime, my son and my grandson must solve it!

Liu Heng believes that he has found a good general for the country. The Xiongnu army retreated, and Liu Heng ordered the withdrawal of troops and promoted Zhou Yafu to lieutenant, in charge of the military power of the capital, and was responsible for the security of Chang'an City.

Zhou Yafu, the real Jiangmen Huzi, the best son of former Prime Minister Zhou Bo. The old generation will fall, and the new generation will rise.
