Kang Zong, born in Beiping, Dingzhou, is known as Yangcheng. Yangcheng is modest and respectful, simple and simple, and treats all ages equally. People from far and near admire his character, and people come to study in succession. The local people had a dispute and decided not to go to the government, but to Yangcheng. A man stole a tree in Yangcheng. Yangcheng saw him, worried that he would be ashamed, so he stepped back and hid. Yangcheng family once ran out of grain and sent servants to borrow rice. The servant traded rice for wine and drank it on the road. Yangcheng was surprised by the servant's delay, so he took his younger brother to meet him. Yangcheng carried him back before waking up on the road. When the servant woke up and deeply blamed himself and apologized, Yangcheng said, "What's so strange about drinking in cold weather?" Shandong Jiedu House heard that Yangcheng was a virtuous man, so it sent messengers to Yangcheng to give 500 fine silks and warned them not to take them back. Yangcheng resolutely refused, and the messenger left the silk and went back. Yangcheng put the silk aside and never opened it again. Just as fellow countryman Zheng Wei was going to bury his relatives, he didn't borrow money from others. Yangcheng knew this situation and gave him the silk. Dezong called him to North Korea, appointed him as the right advice doctor, and specially sent Yang Ning, a captain of Chang 'an, to his home to send him bundles of silk. When Yangcheng was not an official, scholars admired his integrity. When he becomes an official and an admonisher, all scholars think that he will be loyal to his duties, and officials in the world are even more afraid of him. After he ascended the throne, other remonstrating officials frequently remonstrated with complicated political affairs, which made the emperor very tired, while Yangcheng invited guests to drink day and night. A friend tried to persuade him not to eat and drink all day. Yangcheng showed his psychology and tried his best to make this friend drink. When a friend refused, Yangcheng first raised a full glass of wine to show his respect. When his friend had to, he had to give him a glass of wine in return. Sometimes he gets drunk and falls on the wine table. Yangcheng sometimes lies drunk in his friend's arms, but he doesn't hear anything his friend says. Yangcheng often pawns wooden pillows and cloth for money. People respect his virtue and compete to buy his things. Yangcheng often says to his two younger brothers, "I can estimate the cost of rice, vegetables and salt for a month first, prepare it first, and take the rest to drink, so I don't have to make up." There are no extra clothes. When his friends praised his beautiful clothes, he was very happy and gave them to others. A man named Chen Chang found that Yangcheng was paid, and he often praised the beauty of money, and he always got something every month. When Pei Yanling framed and exiled Lu Zhi and other officials, because the emperor was very angry with Lu Zhi and others, no official dared to speak to the emperor. Yangcheng heard this and said, "I am an admonisher. I can't let the emperor kill innocent ministers." So Wang Zhongshu went to court with him, sternly reprimanded Pei Yanling's crimes, and enthusiastically defended Lu Zhi and others for many days. The emperor was furious and called the prime minister to cure Yangcheng. Shunzong was the crown prince at that time, and launched a rescue to Yangcheng. As a result, Yangcheng was exonerated. But the emperor's anger did not disappear, Pei Yanling should have become prime minister. Yangcheng threatened: "If Pei Yanling is made prime minister, I will cry in the court in white linen and ruin it. In the end, the emperor did not appoint Pei Yanling as the prime minister, which was due to Yangcheng. Yangcheng went out of Beijing to be the secretariat of Daozhou. Dwarfs are born in Daozhou and pay tribute to the imperial court every year. Yangcheng sympathizes with them. Where will you go? You won't pay tribute. The emperor sent someone to invite him, and Yangcheng presented a memorial and wrote, "Daozhou people are short." If you want to pay tribute, I don't know which ones can. "From then on, no more tribute. The state's taxes were not paid on time, and the observation made many accusations. The observation office sent a judge to urge the tax. When he arrived in Daozhou, he was surprised that Yangcheng didn't come out to meet him. He asked the local officials about it. Officials said: "Yangcheng thinks he is guilty and imprisons himself in prison." The judge was surprised and ran into the prison. He met Yangcheng and said, "What's your crime? I was just ordered to pay my respects to you. "The judge stayed in Daozhou for a few days, but Yangcheng didn't dare to go back, so he lived outside the museum and stood by. When the judge sees this, don't leave quickly. Shunzong acceded to the throne and wanted to recall Yangcheng, which died at the age of seventy.
