He belonged to a branch of Changdi, a giant living in northern China. The surname of Lai (also said to be surnamed Qi), in the Xia Dynasty for the Fengfeng clan, the Fengfeng clan in present-day Deqing, Zhejiang, later migrated north; In business, it is Wang Mang's, and in Zhou, it is concealed. The specific location of the country has not been determined, probably in the area from Zhuolu in Hebei Province to the northern part of Shandong.

He is arrogant, fierce, belligerent, and extremely aggressive. The people looked down on foreigners, so they divided them into dwarf winter melons, dwarf melons and other dwarf melons according to their height. For these reasons, they isolated themselves, they had no allies, and the country was not strong.

As early as the reign of Duke Wu of Song (BC765-BC748), he invaded the Song State on a large scale, and Duke Wu of Song ordered Emperor Situ to lead an army to meet the enemy. At that time, the class was in the royal Rong, the son Gu Sheng was the right of the car, and the father of Si Kou Niu was the horse. The Song army encountered the Yan army at Changqiu (present-day Fengqiunan, Henan) and immediately launched a fierce confrontation with the enemy.

In the end, the Song army won a crushing victory at the cost of the lives of the commander and his chariot right, his chariot and a large number of soldiers, and the Emperor was also killed in battle, and the corpses of him and many of the invaders were hung on the city wall for public display. This war greatly damaged the vitality of the enemy, and the enemy country took advantage of the fire, and the national strength gradually declined.

Although he survived, he was seriously injured and could no longer go to battle. In order to reward him for his merits, Duke Wu of Song arranged for him to collect a gate tax for a city gate, and used a part of these taxes as his food, and this city gate was later named "Yunmen".

For more than 100 years after that, he never made much of a fuss.

In the 11th year of the reign of Emperor Lu Wen (616 BC), the Emperor finally began to break out, and succeeded in showing the world how people can kill themselves.

In the autumn of this year, the Yan army invaded the state of Qi under the leadership of the monarch Qiaoru and his two brothers, Leopard and Yu. The main purpose of the enemy army was to loot, not to conquer cities, so the army did not attack the heavily defended large cities, but only plundered along the western border of Qi and moved south.

The Lu people realized that they were the enemy's next target and began to assemble their armies and prepare for battle. Lu Wengong divined the candidates for the commander of the army, and as a result, his uncle and grandson Dechen were fortunate enough to be elected. Uncle Sun Dechen said: "Emperor Father of Song once rode a chariot to meet the Emperor, and today the minister wants to follow the example of the Emperor Father and annihilate the enemy!" ”

Chariots were not standard for the armies of the princes; But Lu Wengong loved to hunt, so he built a particularly powerful chariot with four of the strongest horses. This car is especially stylish when galloping on the hunting ground, and everyone dreams of being a part of the chariot.

Lu Wengong was a famous marksman, he thought that he was invincible in the country, and no one dared to surpass him. But he happened to hear that his uncle and grandson Dechen's archery skills were higher and stronger, so he was very unconvinced, so he took out the chariot as a bet to compete with the other party.

Uncle Sun Dechen happily responded to the battle, and the two divided the game into three according to the rules prevailing at the time. After a game, the two sides were evenly matched, and Lu Wengong proposed to exchange bows and arrows for another game. With a malicious smile on his face, Uncle Sun Dechen handed the bow to the other party. As a result, Lu Wengong regretted it as soon as his fingers were on the bowstring: Uncle Sun Dechen's bow was really too hard.

He barely managed to complete two projects crookedly. In the third event, his fiery deltoid and biceps muscles almost set his clothes on fire, and he had to give up the race, but his uncle and grandson Dechen were unmoved, ignoring Lu Wengong's depressed mood and completing the whole event in an orderly manner.

As a result, the chariot was owned by his uncle and grandson.

Uncle Sun Dechen led a hundred chariots and an army of infantry to pursue the enemy, at that time Hou Shuxia was the royal Rong, Mianfang's nephew was the right of the car, and the rich father's final nephew was the horse.

The height of the uncle and grandson Dechen and the three people in the same car was not lost to the Yan people, and the four of them stood on the chariot like gods, and Lu Wengong exclaimed: "You are all giants of the Lu country!" Indeed, he is worthy of a widow's chariot. ”

Uncle Sun Dechen corrected him and said, "It's the minister's chariot." The Lu army marched from the north gate of Qufu City and went straight to the enemy.

The Lu army invaded the state of Lu from the west, and the enemy had already looted a large amount of property when the Lu army set out; Qiao Ru believed that the purpose of this operation had been achieved, so he ordered a retreat. Escorting a large number of people, livestock, and property, the army slowly embarked on the road of no return to China.

On the night of 2 October, the Lu scouts reported that they had spotted a large enemy camp near Xianyi (present-day Juyenan, Shandong), twenty miles ahead. Uncle Sun Dechen was anxious, because after Xianyi, he entered the territory of Weiguo; It doesn't matter if the Lu army crosses the border, it is called an "invasion". He decided to settle the battle no later than tomorrow. Uncle Sun Dechen immediately gathered the army, ordered the ranks, the horses picked up the bells, the flags and drums, left the baggage, and advanced lightly.

At that time, the army was encamped in an open field. The retreat path they chose was far from the vassal capitals and large cities, and they were confident that they would not encounter the regular armies of the enemy countries, so they were almost unfortified.

The Lu army stopped advancing on the back of a hill three or four miles from the enemy camp, a natural barrier that cut off the sight of both sides. At this time, the camp was brightly lit and disorderly, and people were noisily drinking and having fun. Uncle Sun Dechen was eager to attack immediately, but Hou Shuxia reminded him that the soldiers had been severely overdrawn after several days of rapid marching, and that they were now hungry; It is better to eat and rest first, and then attack at dawn.

Uncle Sun Dechen saw that the sergeants were indeed fighting and looking at him, and his face was full of exhaustion, so he ordered to rest.

When dawn was about to break, the Lu army took advantage of the last darkness before dawn to advance to the enemy camp, with infantry in front and chariots behind. The east had turned white, and the enemy camp was in shambles, with some campfires still smoking, and utensils for food and wine were thrown everywhere. Even though it was winter, there were still a large number of enemies who were lying in the open air and sleeping soundly.

The Lu advance was only a few hundred meters away from the target, and at that moment someone in the battalion spotted the enemy, shouting and knocking on everything that could make a sound. The hounds in the camp also barked wildly, and the enemy woke up one after another, but their eyes were hazy, and the long night of bitter drinking made them dizzy, and many of them got up and fell down, and could not stand steadily.

The Lu army stormed the camp with a single charge, and then a terrible massacre took place. The freed princes and captives also joined the warband, and they hated their enemies more than the Lu people, and their attacks were more ferocious.

Most of the enemy were still unsober, swaying and unresponsive, and the long weapons in their hands were particularly clumsy to wield. The enemy's tall, unprotected body and bare head became excellent targets for the Lu army; Lu ** soldiers use short weapons, they are agile and flexible, two or three groups of two or three at the same time to attack an enemy, in a short period of time to put down a large area.

He saw that the enemy was gradually unable to lower and move towards the rear camp, so he led an army around the rear of the camp and prepared to block the fleeing enemy.

Uncle Sun Dechen's target is the enemy leader Qiaoru. Although Qiaoru put up stubborn resistance, under the ferocious offensive of the Lu army, he finally had to lead the defeated army out of the back door. Uncle Sun Dechen was overjoyed and immediately drove to meet the battle. Qiao Ru rode a tall and sturdy war horse, rampage through the fighting crowd, slashing and slashing the enemy to his heart's content.

Uncle Sun Dechen pulled the bowstring and shot an arrow, and the sharp arrow broke through the air, piercing Qiaoru's left shoulder, and the powerful impact directly lifted him off the horse.

The rich father's nephew jumped out of the chariot and rushed towards Qiao Ru. Qiao Ru struggled to stand up holding on to a big tree, and the second arrow of his uncle Dechen arrived, which pierced his right shoulder and pinned him to the tree. Qiao Ru roared angrily and forcibly pulled his body out of the shaft of the arrow; But the rich father's nephew also arrived, and he pierced him in the neck from the bottom up with a halberd, and nailed him to the tree again. Qiao Ru immediately lost his breath, and the rich father's nephew cut off his head and returned to the chariot, carrying his head with a halberd and shouting: "Qiao Ru is dead!" Qiao Ru is dead! ”

Qiao Ru's brother Leopard was carried away by the rage and drove his horse towards the chariot. Uncle Sun Dechen smiled (this smile had appeared when he tried archery with Lu Wengong), and bent his bow to shoot an arrow. The arrow pierced his neck, and the leopard fell from his horse. Seeing that the two commanders were killed, the soldiers had no intention of fighting again, and many of them laid down their arms and surrendered to the Lu people. Those who refuse to surrender will either fight to the death, or fight their way out and flee.

The battle lasted until near noon, and the army was almost completely annihilated, and the casualties of the Lu army were not small. When the Lu people dragged the corpses of the enemy together, they couldn't help but be shocked by the strength of the enemy's body and the results they had achieved, and they were glad that they had survived at the hands of such a powerful enemy.

The Lu army returned in triumph, and the heads of the enemy were brought back and hung on the city gates, where they hung until the terrible things could not be recognized. Qiaoru's head was later buried outside the Ziju Gate on the west side of the North City.

In order to commemorate his glorious achievements, Uncle Sun Dechen named his eldest son Shusun Qiaoru, and his second son was called Shusun Leopard.

After this battle, the national strength weakened again. After Qiaoru's death, Qiaoru's younger brother Rong Ru was appointed as the king. In the spring of the following year, he was attacked by the other Rong Di who beat them like water dogs, and the people fought a bitter and bitter war, and finally repelled the enemy.

In the second year of Lu Xuangong (607 BC), Rong Ru and his brother Jian Ru led an army to invade Qi again. The general of Qi, Prince Chengfu, led his division to defeat the enemy army outside the city of Zhoushou, and captured Rongru's head and buried it outside the north gate of Zhoushou.

Under the leadership of Jian Ru, the remnants of the people fled in a hurry, and when they passed through the country in the process of escaping, they were stopped by the guards. You must know that among the Chinese princes, the patriots hated the Di people the most. The defenders launched a thunderous attack and slaughtered the enemy to the ground. Almost no one survived this time.

At this time, the national strength of the country had declined, and the country was no longer able to resist the attack of foreign enemies, so the people of the country took refuge in the country of Lu. Luzi gave Yan Ru a piece of land, and he became a vassal of Lu State.

In the fifteenth year of Lu Xuangong (BC594), Jin Jinggong launched a full-scale war against the Lu State, and the people of Wu, as an important part of the Lu army, caused great casualties to the Jin army in the war. After the Jin people were destroyed, they executed the burning Ru and moved the remnants of the people to the country, and the people were destroyed.
