After Zhou Fei, the Hou of Guangnian, became the Taishou of Hedong County, he adopted an active economic policy, suppressed the scholars, encouraged farming, recruited displaced people, and expanded infrastructure construction, so that the economy of Hedong County developed by leaps and bounds.

The Linfen Basin and Yuncheng Basin of Hedong County have been developed agricultural planting areas since ancient times, with fertile land and convenient irrigation.

Zhou Fei set up the pastoral office of Bingzhou in Anyi, Hedong County, so that the center of gravity of Bingzhou shifted to the south, and the defense of Bingzhou with the defense of Xianbei in the north was shifted to the west, mainly to defend Qianghu.

The economic development of Hedong County has provided material support for the expansion of the army.

After Zhou Fei served as the governor of the state, he integrated the officers and soldiers of Taiyuan County and Shangdang County, eliminated the old and weak, and retained 500 cavalry and 1,500 infantry in each county; Only 100 officers and soldiers remained in each county, and some of the strong ones were transferred to Hedong County as soldiers; The remainder is to be dismissed as the people.

Emphasis was placed on strengthening the military forces of Hedong and Shang counties; Zhang Meng, the governor of Xihe County, organized 5,000 cavalry for the attack and 3,000 infantry for the defense of the city.

After Lu Yi was transferred to the Taishou of Hedong County, he continued to directly govern his Xiandeng camp, which was mainly composed of 1,000 people he brought from his family, joined part of the Qianghu and Hanmin, and expanded to 2,000 people, becoming a small number of troops, but extremely strong in combat power, and its combat effectiveness was no less than that of the trapped camp.

The personnel and army were adjusted, and Guan Hai continued to serve as the governor of Hedong County, and the number of officers and soldiers under his jurisdiction increased.

Xu Huang's station continued to be in Xiayang City, and Song Xian's station was adjusted to Fushi City, and he was appointed as the governor of the northern part of Shang County; Gao Nu garrisoned two military commanders, who managed the cavalry and infantry respectively.

The cavalry and infantry under the jurisdiction of the original Luyi were divided into three parts, one part was stationed in Gaonu City, one part was returned to Xu Huang, and one part was strengthened to Guan Hai; This brought the number of cavalry under their command to 25,000.

After receiving the emperor's order and Gao Shun's letter, Zhou Fei negotiated with Lu Yi and decided to transfer Lu Yi to the Taishou of Anding County and Zhang Meng (Zhang Niujiao) to the Taishou of Beidi County.

He made Hao Zhao, a young general in Taiyuan, the commander of Xihe County, lead 2,000 cavalry and 2,000 infantry to garrison Lishicheng, and choose the opportunity to expand the number to 5,000 people.

Hao Zhao was a young general excavated by Zhou Fei when he was reorganizing the officers and soldiers of Taiyuan County, and he was very happy that he was promoted to the military commander.

Hao Zhao is nine feet long, majestic, powerful, with two belts and two sheaths, and can shoot left and right.

According to the emperor's order, Zhou Fei'an concurrently served as the Taishou of Hedong County.

In order to strengthen the military strength of Lu Yi, Fu Zhu decided to regroup the army under the jurisdiction of the former Lu Yi, with 10,000 cavalry, 2,000 soldiers of the Xiandeng battalion and 5,000 infantry, and these officers and soldiers will be stationed in Anding County with Lu Yi; The officers and soldiers under Zhang Meng's jurisdiction remained unchanged

Donghan Valley, South Kunwu, West Sanguan, North Xiao Pass, is one of the four major passes in Guanzhong, and one of the four passes is North Xiao Pass, also known as Han Xiao Pass.

Since the Warring States Period, Qin and Han dynasties, the Xiaoguan Ancient Road has always been the main channel for military, economic and cultural exchanges between Guanzhong and the north. Xiaoguan has a special geographical location, out of the southeast can directly drive the Guanzhong Plain to a large area of fertile soil, north across the Yellow River to the vast prairie, to the west can lead to the four counties of Hexi and other vast areas.

Xiaoguan, southeast of present-day Guyuan, Ningxia; The Liupan Mountain Range lies in the northwest of Guanzhong and is its northwest barrier. The passage into Guanzhong from Longshang is mainly the valley lowland cut by the Wei River, Jing River and other rivers. The direction of the Wei River is more steep, while the direction of the Jing River is relatively easy. Xiao Pass stands in the Liupan Mountain Pass, guarding the passage from the direction of the Jing River into the Guanzhong Plain. Xiaoguan is an important pass in the northwest of Guanzhong, which protects the safety of Guanzhong and the northwest.

Gao Shun's choice to occupy Xiaoguan not only had important military significance, but also important economic interests.

Zhou Fei, Fu Zhu and Lu Yi and others are determined to win Xiao Guan.

This is the first time that Fu Zhu has planned a large-scale battle, and he is even more cautious, thoughtful, and detailed.

Zhou Fei had long planned to recover the two counties, and sent a large number of scouts to the two counties to inquire about the news, and knew the local situation well.

Qianghu has occupied the two counties for a long time, and the strength of the Qiang people in the two counties is very strong, and they can form more than 100,000 cavalry, and even Dong Zhuo's strength is so strong that he can't successfully recover the two counties.

If it is a head-to-head duel, concentrating all of Zhou Fei's military forces is not the opponent of the two counties and Qianghu, and it must adopt an effective strategy, which is difficult to frustrate.

After thinking about it, he decided to take a step-by-step approach, gradually recovering the lost territory, and used this battle as a whetstone for recruiting and training troops, and when the war was over, he would not only recover the lost territory, but also train a strong army.

If the southern part of Beidi County is recovered this winter, it will be possible to use next year's year to recover the southern part of Anding County.

Anyway, now Zhou Fei has the support of Gao Shun, has deep pockets, does not worry about financial problems, and tries his best to deal with Qianghu, gradually wearing down Qianghu's strength and patience.

First of all, to obtain the support of the champion Hou Gaoshun, the method of frustration is very simple, that is, let Guan Yu lead 10,000 cavalry, plus 10,000 cavalry of Xiongnu Shan Yu and 10,000 cavalry of Xianbei King Kuitou, to plunder Beidi County again, threatening the safety of Qianghu's back in Beidi County.

In winter, there was nothing to do, and the Xiongnu Shan Yu and the Xianbei King both readily agreed, and they were very cooperative with the Han army's operation, in their opinion, they could plunder if they could, and even if they could not loot, the Han army would not treat them badly.

So, in mid-December, Guan Yu led 30,000 cavalry from Heyin County, Zhang Yang led 2,000 cavalry with the army, and Zhou Cang sat in Heyin City to ensure logistics materials.

The army marched all the way west, passing through Shuofang City, first recovering Guangmu County, which was occupied by the Xiongnu Youxian King, and then reaching Linrong County, which was controlled by the Xianbei people, and then going south and entering the territory of Beidi County.

Secondly, Song Xian was asked to gather troops to contain the Xiongnu Youxian Wang's department, so that there would be no abnormal movements.

Again, in order to ensure victory, Zhou Fei and Fu Zhu decided that Xu Huang would lead the 20,000 cavalry under his jurisdiction to assist; Guan Hai stayed in Anyi to ensure the logistics baggage; Zhou Fei personally sat in Xiayang City; Frustrated with the army.

Zhou Fei's authority to Lu Yi was that the cavalry could be expanded to 20,000 and the infantry to 15,000; Zhang Meng's authority was to expand the cavalry to 15,000 and the infantry to 10,000; If this is the case, both of them have the power to protect themselves, and if the Qianghu army comes to attack, they can also hold out until the arrival of reinforcements.

Finally, he sent someone to contact Dong Zhuo and asked his army to support the wind on the right to contain Qianghu. Dong Zhuo had a good relationship with Zhou Fei, and he also needed to rely on the grain traded from Zhou Fei; So after Dong Zhuo received the information, he immediately sent 20,000 cavalry to garrison Duyang County, which could not only facilitate the support of the Battle of Chencang, but also befriend Zhou Fei and Gao Shun, and contain the Qianghu people in Anding County and Beidi County.

At the beginning of December, the troops had assembled in Xiayang City and were ready to go.

Fu Zhi first ordered Lu Yi to lead the army under his jurisdiction as the vanguard, enter Diaoyin County in advance, build roads and bridges, and build camps to prepare for the arrival of the large army.

In mid-December, Fu Zhi, Xu Huang and Zhang Meng led the army to Diaoyin City, and after a short rest, they ordered Zhang Meng to lead 5,000 cavalry to take the lead in Beidi County.

After the loss of Northland County, he migrated to Zuo Feng Yi; At this time, Beidi County was no longer owned by the Han Dynasty, and the situation in the county was complicated, there were both Beidi Qianghu, Beidi Qianghu was a mixed Qiang people living in Hu and Han, Hu and Han accounted for half of the population, and there were Hu tribes, and Hu tribes were divided into Beidi Qiang and Beidi Hu; Beidiqiang takes Malan Mountain as the gathering place, and connects with Fengyi and Beidi two counties in the south; Beidihu refers to the Lu Shuihu, Xianbei, Xiongnu and others who flowed in the territory of Beidi County during the Han Dynasty; Once the rebellion is intruded, the Qiangs and Hus of Beidi will mix into one, and the well will cause the Qianghu living in Beidi County to respond and cause chaos together.

According to the plan of Fu Zhu, the battle for recovering the southern part of Beidi County was attributed to Zhang Meng, and then Zhang Meng was stationed in Beidi County as a logistics supply base for the recovery of the southern part of Anding County; The battle to recover Anding County is attributed to Lu Yi; He and Xu Huang were the helpers, assisting them in recovering Beidi County and Anding County respectively.

Lu Yi and Zhang Meng were very eager for battle merits, and they had no objections to the arrangement of the frustrated award.
