Who knows the specific situation of Wu Jiajun in Song Dynasty? Tell me!

Wu Lin (1102-1167), a national hero, was born in Gan Long (now Jingning, Gansu). Wujun's younger brother. He is smart and brave, and together with his brother Wu Jun, he became a famous anti-gold general. During the anti-Jin struggle in the Southern Song Dynasty, his brother Wu Jun made great contributions to the defense of Qinlong and the protection of Bashu. He was a famous patriotic general in the Southern Song Dynasty.

At the beginning of Shaoxing, Wu Lin and his brother Wu Jun defended Sangyuanguan, Raofengguan and Xianrenguan, and defeated the nomads. Jin Yan Hong Liang invaded the South. Led the troops to supervise the war, recovered the sixteen state armies under the jurisdiction of Qin, Feng and other roads, and made meritorious deeds in defending Shu. He conferred the title of Wang Jianyan of Xin 'an County for three years (1 129), and Wu Lin and his brother Wu Jun were also appreciated by Zhang Jun of Fu Xuan, Shaanxi Province. After that, the two brothers fought side by side and got promoted together. After the death of his elder brother Wu Jun, Wu Lin took over his elder brother's mission, became the main force of Shanxi's anti-gold war, and was promoted to commander of Dragon God No.4 compartment. In the tenth year of Shaoxing (1 140), when the "peace talks" were being celebrated with the traitors, the Jin people tore up the peace treaty and divided the troops into four ways. Under the command of the head coach Jin Wushu, they launched an all-round attack on the Southern Song Dynasty. Jinbing soon occupied many counties in Henan and Shaanxi. Then, Jin will lead the nomadic people in the western regions, cross the Yellow River, capture Chang 'an and take Fengxiang directly. At this time, only Hu and Wu Lin, who have the right to announce Sichuan affairs, are stationed in Hechi, and the situation is very critical. Hu Shi will urgently convene various generals to discuss defensive measures. Sun W, the staff officer, suggested that Hechi could not defend and should surrender to the Immortal Academy. Wu Lin thinks that Sun W's ambition is getting bigger and bigger, so she destroys his prestige. He said angrily, "Confucianism can kill the army." And voluntarily "please don't argue." Under the command of Wu Lin, the first battle won a great victory, which dealt a blow to the arrogance of the 8 Jin Army, prevented the enemy from advancing westward and saved the crisis in Shaanxi. The imperial court promoted Wu Lin to be the military envoy of Zhenxi, and named the bodyguard Hou Yu as the capital. Wu Lin also summed up and innovated a new method of warfare in the practice of fighting against the 8 Jin Army, named "array method", which specifically attacked the enemy cavalry stormtroopers. It was fruitful and defeated the Jin army repeatedly, and played an important role in the northwest battlefield.

Jin will unite Hu Zhan and Bu Zhu with 50,000 troops, which is a great threat to the war situation in Shaanxi. Wu Lin fought well and demanded that the enemy be driven away. Hu Shi will ask him what moves to use to defeat the enemy, and Wu Lin will say "matrix method". The so-called base formation method means that spearmen sit in front and are not allowed to stand. The strongest archer knelt behind, and the archer was the last. When the enemy is a hundred paces away from the position, the archer shoots first; At step 70, the strong archers volley. When the enemy rode in the cold, the pike stabbed the enemy's horse and rider. At the same time, when deploying, first connect the cavalry with iron hooks and cover the front. When the deployment is completed, the cavalry will retreat.

In the 11th year of Shaoxing (1 14 1), the Southern Song Dynasty signed a peace treaty with Jin. Since then, although Song and Jin were in peace talks, Wu Lin never let her guard down for a moment, just like in wartime.

In the thirty-first year of Shaoxing (1 16 1), the gold master mobilized 600,000 troops and personally led his troops south in an attempt to destroy the Song Dynasty in one fell swoop. It took only 1 month to reach Hezhou (now Anhui Province-Hexian County) on the north bank of the Yangtze River, which shocked the ruling and opposition parties in the Southern Song Dynasty. That year, Wu Lin was 62 years old and was ill. Song Ting appointed Wu Lin as Fu Xuan's ambassador to Sichuan and recruited ambassadors from Shaanxi and Henan at the critical moment when the Nomads were under siege. Wu Lin commanded on the western front, and successively recovered Qin, Gansu, Shang and other states, which attracted a large number of nomads from the south and eased the pressure on the southeast battlefield.

In the first year of the main road (1 164), Wu Lin was recalled to Beijing and received warm hospitality from Song Gaozong and Song Xiaozong. He was also named a teacher and the king of Xin 'an County. Soon, I was out of town and went to Xingyuan House. After he came to Hanzhong, he repaired the ancient weir and irrigated thousands of hectares, which benefited the local people a lot. After three years on the main road (1 166), Wu Lin died at the age of 66. A legacy to the master, a letter to the king.

Wu Lin has been defending Shu for more than 30 years and has made outstanding achievements.

Wu Lin is brave and upright, from a pawn to a general, guarding Shu for more than 20 years on behalf of his brother, which is an important aspect. During his long military career, he maintained close and friendly relations with soldiers and won the trust of soldiers and people. He has two papers on the art of war. He thinks that the nomads from the army have four advantages and I have four disadvantages. In practice, we should pay attention to using my weakness to control each other's advantages. Use units to control their cavalry, use repeated battles to control their perseverance and heavy armor, use strong bows and crossbows to control their bows and arrows, and use distant seals to force the weak. Know yourself and know yourself, and you will win every battle. So, in front of the strong enemy, he looked at the fighter plane and used Sun Bin's three-pronged method flexibly, "weak first, then strong", and small wins big. Lose big with small. In the selection of generals and personnel, we insist on selecting talents and appointing people in practice. "It is difficult to know an officer's ability unless you try." We reward them according to their performance and hire them according to their quantity. Therefore, he won great popularity and became a well-deserved leader among the anti-Jin generals in the Southern Song Dynasty.

In the 10th year of Shaoxing (1 140), the martyr's shrine of the King of Wu, which was built in Xianrenguan in the first month, was occupied by An Bing in 68 years after the death of the King of Wu and changed to "Anci". Tomb of Wu Wang in Nanba, Lueyang (tomb of Wu Lin), the tombstone of Xiao Zong's imperial book "Safeguarding the people and making great achievements".
