The word Shengqing was born in Chen Wuping. At the age of twelve, Seo Woo was able to study history. He lost his father in his early years and took care of his grandmother. The county recommended him as Shunsun. Chen Guoxiang thought he was a rare talent and wanted him to be an official. Seo Woo declined, saying, "Grandma is ninety years old. Without me, no one will support her. " Guo Xiang just gave up. Later, Seo Woo's grandmother died, and Seo Woo's mourning period passed. He was recruited into Qiu Lixiu's house as a doctor.

When the Qiang army invaded Wudu, Empress Dowager Deng thought that Seo Woo had a general plan, and appointed him as Wudu Prefecture. And met him in the guardian hall and gave him a generous reward.

The Qiang leader led thousands of troops to stop Seo Woo's troops in Chencang Road and the small valley. Seo Woo immediately ordered his entourage to stop moving forward, claiming that he had asked the court for reinforcements, and they would go together as soon as the reinforcements arrived. When the Qiang people heard the news, they went to neighboring counties to plunder separately. Seo Woo, while the Qiang troops were scattered, let his guard down, marched for hundreds of miles day and night, and ordered the soldiers to dig two stoves each, and then each person dug two more every day. Qiang people (seeing more and more pits every day, thinking that the Han army has reinforcements) dare not approach. Someone asked Seo Woo, "Sun Bin reduced the number of stoves, but you increased them. According to Sun Tzu's art of war, we should guard against accidents for 30 miles a day, and now we are marching for 200 miles a day. Why? " Seo Woo replied, "There are many enemies, and we are serenading. Walking slowly is easy to be caught up, and it is hard for them to think of walking fast. Seeing that our stoves are increasing every day, the enemy will definitely think that reinforcements are coming to meet us. We have a large number of soldiers and are moving fast. They must be afraid to chase us. Sun Bin is showing weakness, and we are showing strength because the situation is different. "

When Seo Woo arrived in Wudu County, there were less than 3,000 soldiers, while there were tens of thousands of Qiang people. They besieged Chiting for dozens of days. Seo Woo ordered soldiers not to fire strong crossbows, but only to shoot with small crossbows. The Qiang people thought that the arrows of the Han army were too weak to shoot themselves, so they concentrated their forces and stepped up their siege. When Qiang soldiers rushed to the gate, Seo Woo ordered twenty strong crossbows to shoot at A Qiang at the same time, and none of them missed. The Qiang people were frightened and quickly retreated. Seo Woo took the opportunity to lead his men out of the city to pursue bravely and killed many enemies. The next day, Seo Woo called all the soldiers and ordered them to go out from the east gate and turn around and enter the city from the north gate. Then he changed his clothes and set out from this gate. That door came in and kept changing clothes to confuse the Qiang people. Repeat this many times. Qiang people don't know how many people and horses there are in the city, and they are more and more frightened. Seo Woo estimated that the Qiang people were going to retreat, so he secretly sent more than 500 people to ambush in the shallow water by the river outside the city, waiting for the enemy to retreat. The Qiang people did escape, and the Han army took the opportunity to intercept and defeat the Qiang army.

At that time, Zhang Fang used his power and was often asked to take bribes. Seo Woo repeatedly asked for an investigation, but he wrote to the court many times, but got no reply. Xu Yu was so angry that he ordered people to tie himself up and throw him into Ting Wei's prison, and wrote, "Today, Zhang Fang acted recklessly, and the country will come again. I didn't want to be in the court with Zhang Fang, so I threw myself into Tingwei's prison and let your majesty know. " After Seo Woo's watch was played, Zhang put a tearful explanation before the emperor, so Seo Woo was removed from his post and sent to Zuoxuetang as a slave. Zhang Fang refused to give up and tried to hurt Seo Woo. Seo Woo was interrogated and tortured four times in two days. The jailer suggested that Seo Woo commit suicide to avoid abuse, but Seo Woo refused. He said: "I would rather die by the torturer's sword and let people near and far know." Eunuchs Sun Cheng, Zhang Xian and others knew that Xu Yu had suffered because of his loyalty to the monarch, and they all requested to meet Shun Di. Sun Cheng said, "Your Majesty hated treacherous officials very much when he started an incident with me, and he knew that the appointment of treacherous officials would lead to national ruin. Now, after he reached the top, he indulged himself in sheltering treacherous court officials. Why did he blame the first emperor for being wrong? Seo Woo, a captain in Li Si, was loyal to His Majesty, but was arrested and detained. Zhang Fang, a servant of China, often prevents corruption and perverts the law. The fact is clear, but he set up a frame for Zhongliang. Looking at the celestial phenomena today, the guest star guards the feather forest, which is a sign that there are traitors in the palace. We should arrest Zhang Fang quickly and put him in prison to prevent a disaster from heaven. Ordered the release of Seo Woo and returned his decree. " At that time, Zhang Fang was standing behind Shun Di, so Sun Cheng shouted at Zhang Fang: "Why didn't the traitor Zhang Fang go down to the temple!" Zhang Fang had to walk a short distance and retreat to the east wing. Sun Cheng added, "Your Majesty, please arrest Zhang Fang immediately and don't let him go to your wet nurse for help."

Shun Di also consulted ministers, and Minister Jia Lang has always been friendly with children, which proved Seo Woo's sin. Shun Di was puzzled and said to Sun Cheng, "Go out for a while and let me think." So, Seo Woo's son and 100 students held flags, waiting to stop Van Gogh's car, kowtowing and bleeding to Van Gogh, telling him that Seo Woo had been wronged. Van Gogh returned to the palace and reported the situation to Shundi. As a result, Zhang Fang was exiled to the frontier for committing crimes, and six people, including Jia Lang, a senior minister, were executed or dismissed from office. Seo Woo was released on the same day. Sun Cheng also wrote a letter saying that Xu Yu had made great contributions, and the wording was very straightforward and fierce. Shun Di was moved. He recruited and appointed Seo Woo as the negotiator. A few days later, he was promoted to the servant of Shangshu.

Xu Yu loves to expose and repeatedly contradict powerful people, so he was scolded nine times and tortured by three punishments, but his strong and upright personality has never changed. In the early years of Yonghe, he was promoted to Shang Shuling and was removed from his official position because of official duties. People in the imperial court read his loyalty and called him up, and it happened that he died.
