Song Taizu (927 ~ 976) was a famous military commander and strategist. Originally from Zhuozhou (now Hebei). In the early Han Dynasty, he joined the army and turned to Guo Wei, the envoy of the Tang Dynasty. Guo Wei proclaimed himself the Emperor of the Zhou Dynasty, and was the head of the imperial East and West classes. In the first year of Xiande (954), in the battle of Gaoping, Ma Jun commanded Fan Ai to retreat because of fear of war. When Chai Rong, the emperor of the Zhou Dynasty, personally broke the battle, he commanded Zhang Yongde to ride the 2000 with the front of the temple at various rates, took the initiative to attack, turned defeat into victory, and was promoted to the front of the temple with meritorious service. Two years later, after the attack of the Zhou Dynasty, (now northwest of Tianshui City, Gansu Province) and (now northeast of Fengxian County, Shaanxi Province) were attacked for a long time. He was ordered to inspect the terrain, analyze the war situation, and said that Qin and Feng were desirable. Sejong followed suit and defeated the Shu soldiers. In recent three years, the Later Zhou Dynasty attacked Nantang, led the vanguard troops to attack Qingliuguan (now northwest of Chuzhou, Anhui Province), broke the retreat of Nantang Army, defeated Nantang Army several times, captured two generals, Huangfuhui and Yao Feng, and captured Chuzhou. Soon, the left-wing army occupied Yangzhou, and the southern Tang army crossed the river to fight back. Zhao Kuangyin led nearly 2,000 troops to defend Liuhe (present-day Jiangsu) with Zhang Yongde, and then beat back more than 20,000 troops from Nantang, captured more than 5,000 people and took command before they ascended to the temple. Later, they were appointed as our national army. In six years, he attacked Liao with Chai Rongbei and moved to the front of the temple to take charge of the imperial army in front of the temple. In October, Chai Rong died of illness, and his son Zongxun succeeded to the throne at the age of seven, and was granted our time to the German army instead. At the beginning of the first month of the seventh year, he was ordered to lead an army to launch a mutiny in Chen Qiaoyi (now Chenqiao Town, northeast of Kaifeng, Henan Province), seize political power and establish the Song Dynasty. In order to consolidate the rule, gradually cut off the imperial army and regain the military power, the Privy Council was set up to take charge of the army and the right to leave the army. The three lawsuits (the former department, the Guards' Ma Jun Division and the Guards' Bu Jun Division) sent troops in a unified way and restricted each other; The elite soldiers from all over the country will be transferred to the capital and incorporated into the imperial army to strengthen the weak branches and weaken the forces of the buffer regions; The imperial army was issued more defensive laws, stationed in different places and rotated regularly, so that its soldiers could not be specialized, thus establishing a system of centralization and strengthening autocracy. Carry out the policy of selecting good soldiers, strengthen training, innovate weapons, be strict in discipline, and continuously improve the combat capability of the troops. At the same time, he began to devote himself to the war of unification. With the overall plan of first south and then north, first weak and then strong, and divided into one, we sent effective generals to guard the border, defend Liao and Northern Han, and send the main force south. From September of Song San year (962) to May of Kaibao year (975), it defeated the regimes of Jingnan, Hunan, Houshu, Nanhan and Nantang successively, basically ending the separatist regime that lasted for more than 200 years since the "An Shi Rebellion" in the Tang Dynasty. Kaibao died nine years ago at the age of 50. During the reign of 16, great achievements were made in establishing military centralization and reforming the military system. To guide the war, we should pay attention to understanding the enemy's situation, dividing and disintegrating, and winning by wisdom.
