In 1925, Shi Yousan was promoted to the rank of commander and led the troops to garrison Baotou, and he took his father to serve him. One day, a sentry played with a gun and injured a common man, and Father Shi was very angry and asked Shi You to shoot the sentry three times. Shi Yousan did not comply, Shi Father was angry on the spot, and publicly scolded Shi Yousan for "forgetting his roots and not filial piety", and Shi Yousan had to kneel down and admit his mistake.

Shi Yousanzi Hanzhang, a native of Changchun, Jilin Province, his family was poor in childhood, his father drove a big car in the Bi family of the large landlord in Changchun, and Shi Yousan often went to the Bi family to visit his father. The landlord of the Bi family saw Shi Yousan's cleverness, so she left him in the Bi family's study to accompany her two sons to study for more than five years.

Although Shi Yousan and the young master were having fun together, he still ate and slept with his father in the long workshop, and wore the worn-out clothes of the young master. Due to the huge disparity between rich and poor, Shi Yousan often felt despised and embarrassed, and after marriage, he suffered from his wife's pungency, and his family life was also very difficult, so he was forced to become a soldier. Shi Yousan's father was very strict, so Shi Yousan, who later developed, often trembled when he saw his father.

Shi Yousan's changes before and after were very large, and in his early years, when he was a battalion commander, he paid close attention to the training of each company and the discipline of the military. Whenever brigade commander Feng Yuxiang pointed out a small problem with a certain soldier during the military parade, Shi Yousan would scold and punish the relevant platoon commander and kneel. At that time, Shi Bu's military discipline and military appearance were very good, so Shi Yousan was very trusted by Feng Yuxiang.

In 1924, Feng Yuxiang was appointed as the Northwest Border Defense Inspector, and Promoted Shi Yousan to the commander of the Eighth Mixed Brigade and concurrently serving as the defender of Baotou Town, at this time he began to show his cruelty and greed for money, and treated his subordinates extremely harshly for the purpose of unscrupulous means. During his stay in Baotou, Shi Yousan made daily friends with local gentry, landlords, and big businessmen, and used force to support the illegal acts of these people.

In Baotou for only half a year, more than 500 people were innocently killed by Shi Yousan's troops, and the local people called Shi Yousan the "King of ShiYan". Not only did he treat the people, But Shi Yousan also killed his own subordinates at will. For example, shi Yousan recruited bandits Su Yusheng, Lama Liu, and Zhao Yuru in Baotou, organized them into three battalions, stationed in the suburbs, were not allowed to enter the city, and ordered the garrison troops to enter the city against the officers and men of su, Liu, and Zhao battalions, regardless of public or private affairs, and killed them all, and hunted down and killed more than a hundred people one after another, until Su, Liu, and Zhao could not bear it and led their troops to defect and leave.

Shi Yousan was extremely lustful and married five wives, in addition to the original match, the second aunt was Huang Fengzhi, the Beijing Opera Garden Huadan Huang Fengzhi whom he married in Xuchangqiang, the third aunt was forced to marry Cheng Mou in Beiping, the fourth aunt was the wife who seduced a certain regimental commander of the Northeast Army, and the fifth aunt was forced to marry Lin Weijun, the daughter of Lin Baishui (who was killed by Zhang Zongchang), the chief writer of the Beijing News in Beiping.

Shi Yousan also liked to raise horses, and when he was the leader of the regiment, he raised several horses, personally named "Great White Dragon", "Black Wind", "Chrysanthemum Green", "Crooked Hooves" and so on. Each horse had to be washed by the guards once a day, and in the summer each horse had a horse coat, showing only the eyes and ears to prevent mosquitoes and grasshoppers, and the horses were slightly filthy, and Shi Yousan beat the guards to the head and bleed. After Shi Yousan became a brigade commander, he raised more horses, and he went to watch the riding exercises as soon as he had free time, until he was promoted to the rank of commander and had a car but still raised a few horses.

Shi Yousanmei pressed up and down, and he had a set of despicable techniques, and Feng Yuxiang was also deceived by him and failed to see the true face of this subordinate. Shi Yousan's career began when he was the commander of the second battalion of the third regiment in Feng Yuxiang's Sixteen mixed brigades. At that time, whether it was gymnastics, coaching, and field movements, Shi Yousan could personally practice and lead by example, and he did have a set of bar frames, wooden horses, sky bridges, wave bridges, and rope climbing. Climbing the city, splitting, shooting, etc., all of them are exquisite, and the soldiers are very impressed. Shi Yousan often held competitions in various companies and platoons, and the winners of individual or small units were awarded a pair of socks or a towel and a piece of soap on the spot.

Therefore, during his tenure as brigade commander and division commander, Feng Yuxiang often inspected Shi Yousan's second battalion. At that time, Li Yuanhong, the president of Beiyang, came to the second battalion to inspect, and the second battalion became Feng Bu's face camp. In his early years of combat, Shi Yousan was also notoriously barbaric, and he often carried a horse whip in his hand and walked in front of the positions of each company to supervise the battle.

In 1920, Feng Yuxiang led his troops to fight in Puyang Village, Xingping, Shaanxi, and the Shaanxi overseer Chen Shufan of the Anhui Clan, and the battle fell into a stalemate, and Feng Yuxiang transferred the second battalion to go. Shi Yousan selected forty brave men from each company, personally gave each soldier a purse into three oceans, and then personally led the charge, followed by the former servants, and defeated the defense line of Chen Shufan's army in one fell swoop.

In the first Zhifeng War in 1922, wu Peifu led the troops and the fengzhi Zhang Zuolin at Changxindian, Wu Peifu asked Feng Yuxiang to send reinforcements, Shi Yousan led the whole battalion to forcibly bypass more than a hundred miles in one night, inserted into the flank of the Feng army, and took the night to let the soldiers go to the four shots, and the Feng army was in chaos. Shi Yousan took the opportunity to lead the troops to attack and won a big victory.

Because Shi Yousan was Feng Yuxiang's old subordinate, and indeed made many military achievements in his early years, although Shi Yousan later betrayed Feng Yuxiang many times at both ends of the rats, Feng Yuxiang still treated this one-handed subordinate differently, and many of the soldiers of Shi Yousan's second battalion later became middle and senior officers of the Northwest Army. After Shi Yousan later became a military commander, he also looked up to the officers and men of the second battalion, and once after Shi Yousan met several soldiers of the second battalion in Baotou Street, he immediately went up to greet him and sent each person a few oceans.

In 1926, Zhang Zuolin, Wu Peifu, Yan Xishan and other northern warlords united to attack Feng Yuxiang's Nationalist army. In order to preserve his strength, Shi Yousan secretly signed a non-aggression agreement with Yan Xishan's Jin army, and later led his troops to surrender to Feng Yuxiang. Later, Feng Yuxiang swore an oath in Wuyuan, and Shi Yousan saw the wind and made the rudder, and fell to Feng Yuxiang again. After that, Shi Yousan repeatedly changed his position until he completely betrayed Feng Yuxiang in the later stages of the Central Plains War.

Feng Yuxiang ruled the army extremely strictly, but adopted a feudal patriarchal management of his subordinate generals, although on the surface he received absolute obedience, but people like Shi Yousan, Han Fuyu and others planted the seeds of betrayal and hatred in their hearts, which was also an important reason for Feng Yuxiang's Northwest Army to finally fail and withdraw from the stage of history.
