Zhang Jian (590-650 AD), courtesy name Shiyue, was a native of Xinfeng County, Tang Dynasty, and was a grandson of Gaozu Li Yuan, whose ancestors were military attachés for generations. Influenced by his family, from an early age, he learned martial arts from an early age, excellent skills, in his youth, with his grandfather to lead the army to fight, heroic and good at war, with military merits as a right guard Lang General, and later promoted to the border pass town of Shuozhou Thorn History (Tang Dynasty prefecture roughly equivalent to the current prefecture level, so the state thorn history is roughly equivalent to the current prefecture-level city mayor position).
At the beginning of the Tang Dynasty, the most powerful ethnic tribe in the northwestern border was the Turkic Jieli Khan, who often plundered and bullied the weak and small ethnic groups of neighboring countries, robbed the people's wealth, and used the monarch to be self-sufficient, privately issued edicts, and even the officials who guarded the border pass in the Tang Dynasty were afraid of his strength and did not dare to act rashly, so the imperial court sent Zhang Jian to touch the border. After he arrived at his post, after observation, he personally understood and grasped the timing and situation, and immediately made a decision, adopting the strategy of "taking the rouge to ke gang"; on the one hand, he resisted the actions of the Turks, on the other hand, he educated the people of the prefecture to develop production, camped the fields and prepared for the famine, and harvested 100,000 huo (10 buckets of grain) a year, so that the people could get food and clothing, live a stable life, and the people of the prefecture supported him. In this way, the Turkic leaders were convinced from the heart and no longer dared to act arbitrarily, thus stabilizing the situation on the frontier. During his term of office, he united with the surrounding Sijie ethnic group and several ethnic minority tribes in northern Mobei to exhort all ethnic groups to live in harmony, vigorously develop agricultural and animal husbandry production, resist natural disasters, use the rich to help the poor, tide over difficulties together, and ensure long-term social stability in the border areas.
After Zhang Jian was transferred to Shengzhou, he took over as an official in Shuozhou, changed his previous policy of handling ethnic relations, adopted a coercive strategy, and became self-sufficient with Han chauvinism, which immediately caused a series of riots among ethnic minorities, and the situation on the frontier was once again tense, which stimulated the dissatisfaction of the Sijie people with the Tang Dynasty. In view of this situation, the frontier officials not only did not reflect on their own mistakes, but actually reported to the imperial court: "Sijie tribal rebellion." The emperor was furious when he heard the news, and was discussing sending troops to recruit, just at this time Zhang Jian was at home with his mother's funeral, and immediately took off his filial piety clothes and went to face the king. He gave the emperor a detailed account of the actual situation on the frontier and asked for an envoy to go and appease him. After receiving the emperor's holy will, he did not want to be a soldier or a pawn, he rode alone to the Sijie area, met with the leader, proclaimed the will of the imperial court, and the big and small leaders understood the divine meeting after listening to it, and they were all convinced, and they were willing to submit to the Tang Dynasty, thus avoiding a war, which was handled very well, was appreciated by the imperial court, and promoted him to the governor of Daizhou.
During his tenure in Dai Prefecture, he led the people to reclaim the land and plant large areas of land that had been deserted by the war for many years with grain, so that the poor border people had enough to feed. He also implemented the "Pingzheng Law" in the local area, purchased the surplus grain of the masses in the good years and stored them in the official treasury, and sold them at a fair price in the famine years to relieve the famine, thus solving the major problem of the masses' livelihood and the state's grain storage and preparation. In his jurisdiction, all ethnic groups produced diligently and achieved unprecedented unity. Later, the Khitan and Goryeo tribes adjacent to Yingzhou in the northeast continued to invade Yingzhou and deliberately provoke incidents, and the imperial court transferred Zhang Jian to be the governor of Yingzhou and the lieutenant of Dongyi.
In fact, this "Pingyi Law" was first proposed by Li Wuxiang Wei Wenhou during the Warring States period when he implemented the change of law. Li Wu pointed out: "The people are very expensive and hurt the people", "the people are scattered when they are wounded"; "even if the peasants are injured", "the peasants are injured, the country is poor". "Those who are good for the country will make the people harmless and the peasants will be persuaded", taking into account the interests of producers and consumers, the way is to level the peace. The ingredients of the year to come are ripe years and famine years, and the state cooks grain in the market in the ripe year, and grain in the famine year to stabilize grain prices. This method of "answering the Wei country, the country is rich and strong", the effect is good.
In 645, Emperor Taizong of Tang personally conquered Goryeo, why did he fight Goryeo? In fact, Goryeo and the Tang Dynasty were once friendly, and in 624 AD, Goryeo Li Yuan also crowned the king of Goryeo as the king of Shangzhu Andegu and the king of Liaodong. However, this Liaodong king of the Tang Dynasty relied on the support of the Turks and Baekje as an ally, and often invaded Silla, which had paid tribute to the Tang Dynasty for many years, and even the edicts issued by Emperor Taizong of Tang ignored them. Apparently because there were allies on his side, he tested the Tang Dynasty, and then Emperor Taejong made up his mind to pacify Goryeo.
Therefore, Emperor Taizong made Zhang Jian the commander of the camp and led the Cavalry to be the forward commander of the Sixth Army. Zhang Jian attacked from the new road, defeated the enemy army, invincible, drove straight to Liaodong, attacked Jian'an City, annihilated countless enemies, made immortal battle achievements, and made great contributions to the stability of the northeast border of sheng tang, and was crowned as the Duke of Anhui City and the protector of Dongyi Capital.
In the first year of Emperor Gaozong's reign (650 AD), Zhang Jian died at the age of 60, and was posthumously awarded the title of Grand Master of the Golden Purple Guanglu. Zhang Jian's three brothers, the brother name master, Feng Da servant, Huazhou Assassin History; brother Name Yan Shi, Feng Zuo Wei Grand General, FanYang Jungong, Dian Yu Lin Jun, 30 years, never had. The three brothers all had battle halberds standing in front of their doors, and they were called "The Three Halberds zhang family, the township is very glorious."
