In the era of warlord division of the Republic of China, although Yan Xishan's Jin forces only occupied one province in Shanxi, they played an extremely important role in the history of the Republic of China by virtue of Shanxi's special geographical location and rich economy. Both the Beiyang warlord forces and Chiang Kai-shek's Nationalist government regarded Yan Xishan as an important target for co-optation. Yan Xishan also took the opportunity to vigorously develop his own power, and the Jin Sui Army became an important military force in China at that time. At that time, the Jin Sui Army was mainly in the hands of the "Four Great Kongs" under Yan Xishan.
IV. Fu Zuoyi

Fu Zuoyi was born in 1895. He graduated from the Baoding Military Academy in 1918 and subsequently joined Yan Xishan's Jin Army. He was the most junior of the four great Kongs under Yan Xishan. Although Fu Zuoyi's qualifications were relatively shallow, his ability was extraordinary, especially in military command. In 1927, Yan Xishan joined Chiang Kai-shek's Northern Expeditionary Army and was attacked by the warlord Zhang Zuolin. Fu Zuoyi led the Jin army to occupy Zhuozhou, and then held Zhuozhou for 100 days without foreign aid. Fu Zuoyi's military ability to attack and defend well has also been recognized by the military circles. If the warlord melee only made Fu Zuoyi stand out, then the fight against the Japanese Kou made Fu Zuoyi famous. In 1933, Fu Zuoyi led his army to participate in the Great Wall War of Resistance and was awarded the rank of general by the Nationalist government. After the beginning of the All-out War of Resistance, Fu Zuoyi led his army to various places, and in 1940, he defeated the Japanese army in Wuyuan and won the Great Victory of Wuyuan. During the War of Liberation, he was appointed commander-in-chief of the North China Suppression Campaign. In 1949, it contributed to the peaceful liberation of Peiping. He became the leader of new China.
Three Yang Aiyuan
Born in 1886, Yang Aiyuan graduated from the Baoding Military Academy in 1914 and joined the Jin Army at the invitation of Yan Xishan. Yang Aiyuan was loyal and prudent, and his prudent duty was deeply trusted by Yan Xishan. In 1927, Yang Aiyuan went to Hunan to fight, and the entire army was destroyed. Yang Aiyuan was not punished but was also promoted and reused by Yan Xishan, and had become an important pillar of the Jin army before the Northern Expedition. In 1928, Yang Aiyuan was appointed chairman of Chahar Province. Yang Aiyuan actively promoted Yan Xishan's political and economic policies as a major official, and led the provincial government of Cha Province. During the Central Plains War, Chiang Kai-shek wanted to bribe Yang Aiyuan, but he still firmly sided with Yan Xishan. After Yan Xishan went down, Yang Aiyuan actively stabilized the interior of the Jin army and avoided civil unrest. After the outbreak of the War of Resistance Against Japanese Aggression, Yang Aiyuan served as the commander-in-chief of the Sixth Army, commanding the Thirty-third Army, the Thirty-fourth Army, the newly organized Second Division, the Second Artillery Regiment and other units, and successively participated in the command of the two major battles of Pingxingguan and Xinkou. After the Battle of Xinkou, Yang Aiyuan gradually gave up military power and served as the chief high-ranking official of Yan Xishan.
2. Shang Zhen
Born in 1888, Shang Zhen was admitted to the Baoding Military Academy in 1905, but was expelled from the Baoding Military Academy because of his membership in the League. After that, he entered the Army Lecture Hall of the Three Eastern Provinces to study, and after graduation, he has been engaged in the revolutionary movement. At the beginning of 1916, he successfully raised Chen Shufan as the governor of Shaanxi and expelled Lu Jianzhang. Suide, who was stationed across the river from Shanxi during the Shang Earthquake, was helpless because it was difficult for him to gain a foothold in Shaanxi, so he led most of his regiment's men and horses to cross the Yellow River in the east and surrender to Shanxi. In 1927, Yan Xishan responded to the Northern Expedition, and the Jin Army was reorganized into the Third Army of the National Revolutionary Army. Shang Zhen served as the acting commander-in-chief of Yan Xishan's 3rd Army and launched an attack on the Feng clan. In July of the same year, he was appointed commander of the 1st Army, and in September he was also the commander-in-chief of the left road of the Third Army. It should be said that although Shang Zhen was the pillar of the Jin Army, he had never been a concubine of Yan Xishan. In 1931, Shang Zhen resigned as chairman of Shanxi Province and broke away from the Jin dynasty. After the War of Resistance Against Japanese Aggression, he participated in the Battle of Wuhan. He successively served as the deputy commander of the Ninth Theater and the commander of the Sixth Theater. He later ended his military career and engaged in diplomatic activities.
