In 529, the land of Shenzhou, in the north is the Northern Wei Dynasty established by the Xianbei Tuoba clan. The royal family changed their surname to Yuan, also known as Yuan Wei. The imperial power weakened, the local warlords rose, and Er Zhurong, the "Dong Zhuo of the Northern Wei Dynasty", took control of the government and slaughtered all sides. Many of the Yuan and Wei royal families were killed, and many fled to the south. Coupled with the peasant uprising, the rebellion of the town border guards, the Northern Wei Dynasty was in danger. In the south, Emperor Wu of Liang Xiao Yan, taking advantage of the internal strife in the north, sent the general Chen Qingzhi to escort Yuan Hao, the prince of Yuan Wei who fled to the south of the Yangtze River, and returned to the Northern Wei to fight for the throne. A vigorous and famous battle was unveiled. The actual head of the Northern Wei Dynasty was the clan Yuan Tianmu, and Er Zhurong were each other's insiders and were in charge of the government. He did not consider the Southern Army to be a strong enemy, and sent the main force to deal with the other rebels. They will pay a heavy price for their underestimating enemies. In April, Yuan Hao attacked Rongcheng from Gongcheng in Huaibei to the north, and encountered the Northern Wei general Qiu Daqian with an army of 70,000 and built nine fortresses to block the way. Chen Qingzhi waved his army to attack, fought from the rising of the sun to four o'clock in the afternoon, took three fortresses, and Qiu Daqian surrendered. Chen Qingzhi, 7,000 people. Taking advantage of this victory, Yuan Hao was proclaimed emperor, Yu Suiyang was proclaimed emperor, Yuan Xiaoji was established, and the Yuan Wei Emperor in Luoyang was challenged. Yuan Huiye, the king of Jiyin in the Northern Wei Dynasty, led an army of 20,000 troops into Kaocheng, Chen Qingzhi attacked, took Kaocheng, and captured Yuan Huiye alive. He is still 7,000 people. The people of the Northern Wei Dynasty were amazed, and arranged for the general Yang Yu to guard Xingyang, Er Zhu Shilong to guard the Tiger Prison Pass, and Er Zhu Shi to guard the dealers. 
In May, Chen Qingzhi attacked Xingyang, which had 70,000 troops, and fought for a period of time, but did not fight. The reinforcements of the Northern Wei Dynasty, led by Yuan Tianmu and others, continued to gather in Xingyang, and the number of men and horses reached a terrifying 300,000. Chen Qingzhi gave a speech to his subordinates: "We have killed many people along the way, everyone knows in their hearts. We have 7,000 people and 300,000 enemies, and we can only survive with the determination to die!He analyzed that the Wei army had a lot of cavalry, and it was necessary to take Xingyang as a stronghold before they closed the siege in order to avoid the doom of the annihilation of the whole army. Chen Qingzhi personally beat the drums, and the soldiers gave it a go and desperately attacked the city. Finally took Xingyang and captured Yang Yu alive. Yuan Tianmu's army surrounded Xingyang City, Chen Qingzhi set up a formation on his back, with 3,000 cavalry and thousands of infantry, and once again broke the Wei army, and the Wei army was defeated and retreated. Chen Qingzhi waved his army to kill the Tiger Prison Pass, Er Zhu Shilong fled, Chen Qingzhi took the Tiger Prison, and the soldiers pointed to Luoyang, the capital of Wei. Or 7,000 soldiers. Luoyang was in a mess. The Northern Wei emperor, protected by his ministers, fled to Hanoi. The princes Yuan Yu and Yuan Yanming, who stayed in Luoyang, took the ** left behind to welcome Yuan Hao into Luoyang Palace, inherit the throne, and change Yuan Jianwu. It is equivalent to that there were two emperors in the Northern Wei Dynasty. The ministers were still mainly in favor of the original emperor. Everything in Yuan Hao is supported by Chen Qingzhi's extraordinary achievements, but he is alone and always in a passive state strategically. Not long after, the Wei army counterattacked Yuan Hao. Hou Xuan, the general who stayed behind in Juyang as a backup, was attacked and killed by the Wei army, and Yuan Hao and Chen Qingzhi were cut off from Southern Liang. Chen Qingzhi continued his myth of winning a hundred battles, and within a few months, he won 32 cities, 47 battles, and all of them. He was also a 7,000 southern soldier. But Yuan Hao soon lost the hearts of the people - Yuan Hao became the emperor, arrogant and proud, appointed villains, and acted recklessly. Chen Qingzhi's subordinates, after Baisheng, were also tyrannical and bullied the military and civilians. The soldiers and civilians of the Northern Wei Dynasty were greatly disappointed. Yuan Hao and Chen Qingzhi were disunited and suspicious of each other, which was even more dangerous. On Emperor Wei's side, Er Zhurong went south, a large army gathered, and the two sides confronted each other across the Yellow River. Chen Qingzhi fought eleven battles in three days, and he was still brave and invincible, and Er Zhurong was also afraid and prepared to retreat. Several generals thought that Yuan Hao was incompetent, and Chen Qingzhi could not support himself and could not retreat. So he secretly crossed the river from Kipshi in the upper reaches of the Yellow River, and gave the Yuan Hao army a hard blow on the flank, and sure enough, the Yuan Hao army collapsed. Chen Qingzhi's eyes couldn't be guarded, so he led his southern army to retreat in formation, and Er Zhurong led the iron cavalry to press tightly. General Chen's luck also ran out, and on the way back to the south, a flash flood broke out on Songgao Road, and Er Zhurong took the opportunity to attack, and 7,000 people were wiped out. Chen Qingzhi shaved off his beard and hair, pretended to be a monk, and successfully escaped from Ruyin back to Jiankang. Yuan Hao was killed, beheaded and sent to Luoyang for public display. At this time, it was not yet July, and it took more than two months from the dispatch of troops to the north to the destruction. Chen Qingzhi's 7,000 troops, with incredible achievements, shine in the annals of history, becoming a miracle that has never been seen before or since. Various legends go on and on. said that Chen Qingzhi's white robe and silver spear, Zhao Zilong is as powerful and invincible, and there is a saying that "thousands of troops and horses avoid white robes". 
Chen Qingzhi's Liang Bing, what kind of heavenly soldier is it, so powerful?Chen Qingzhi is a scholar, he can't pull a strong bow or ride a fierce horse. But he was good at strategy. Chen Qingzhi was born in a poor family, and in the era when the Northern and Southern Dynasties emphasized the family system, it was even more difficult to transcend the class and enter the upper class. Chen Qingzhi's level of Go is quite good, and he is Xiao Yan's accompanying student at the beginning. Xiao Yan firmly believes in Buddhism, and he said that after fifty, he will not be close to women. What are you doing when you can't sleep in the middle of the night?Play chess!Chess addiction is very big, and you have to play until dawn. It is estimated that the leaders are addicted to the Xi of big chess, forcing others to play chess with him, and the others are miserable, only Chen Qingzhi is on call, accompanied to the rooster, and is not sleepy at all. The leadership was very satisfied. When Xiao Yan became the emperor, Chen Qingzhi also became an idle official invited by the court. The generals of the Liang Dynasty were divided into 24 classes. Emperor Wu of Liang gave Chen Qingzhi a general of the 6th squad Xuanmeng to lead the troops to the front line. This time, he has trained a super celebrity. He was very talented in fighting. Some battle-hardened veterans of the Northern Wei Dynasty were suffocated under this young general who had just debuted. Within a few years, he became a master on the battlefield. In October of the seventh year of Datong (527), Wei and Liang fought again in Wuyang. Cao Zhongzong, commander-in-chief of the Liang army. Chen Qingzhi suggested taking advantage of the unstable foothold of the Wei army to beat him first. No one responded. Chen Qingzhi led 200 elite cavalry under his command to approach the Wei camp and give the Wei vanguard a head-on blow, causing the enemy to panic. Then calmly retreated and connected with the rear army. This boldness, this idea, is the same as Zhang Liao's blocking of Sun Quan in the Battle of Hefei. After fighting for more than a year, Wuyang was still under the Wei army, the Wei army reinforcements outflanked the Liang army's rear road, and Cao Zhongzong and others discussed retreating. Chen Qingzhi took up the envoy and persuaded everyone: "After a year of fighting, now withdraw the army, all the previous achievements are wasted!"In the art of war, it is said that putting the enemy to death and then revitalizing, waiting for the enemy to encircle, it is the time for us to break the enemy!"The Wei army built thirteen cities, and Chen Qingzhi launched a surprise attack at night and took four cities in one fell swoop. Fearful of the might of the soldiers, the defenders of Vortex Yang City surrendered. Chen Qingzhi sent 30 surrendered soldiers to the Wei army battalions to spread the news of the surrender of Wuyang;After that, let the captives go ahead, and the army then launched a general attack with drums. Sure enough, when the Wei army heard that several cities had surrendered, the army was in turmoil, and the Liang army burst out with super combat effectiveness, conquering the remaining 9 cities of the Wei army in one fell swoop, and breaking the enemy army. The corpse of the Wei army, blocking the vortex. Liang Jun won a great victory, and Chen Qingzhi became famous. 
Therefore, the brilliant achievements in this Northern Expedition were certainly due to the factors of disunity within the Northern Wei Dynasty, but Chen Qingzhi's personal ability was decisive. Because of this Northern Expedition, it was greatly used by Emperor Wu of Liang, and later fought with the north many times and fought many famous generals. For example, Hou Jing, who later made a big fuss in the south of the Yangtze River and forced Emperor Wu of Liang to death, was defeated by Chen Qingzhi. In the fifth year of Datong (539), Chen Qingzhi died. Something:
To borrow the answer of a friend @ old gun:
Lao Wang added: Zhou Yu is not counted, Zhou Yu of Emperor Wu of Liang should be Wei Rui.
