(128—— 169), Zong Lin, was born in Jiexiu, Dayuan County, Eastern Han Dynasty. Poor family, lost his father in his early years, and lived alone with his mother. When he grows up, his mother wants him to find a job in the county government and change his past embarrassing situation. However, Guo Tai, who has always been ambitious, didn't want to associate with those scumbags in yamen, so he didn't obey his mother's orders and attended Qu school.

Guo Tai is knowledgeable and has a keen insight into the world. He deeply felt that the regime of the Eastern Han Dynasty was crumbling, eunuch politics was getting darker and darker, and the dynasty building would collapse, which was difficult to reverse. Therefore, sex is sweet and retired, lighter than official career, like a cloud. Emperor Huan is under construction, too often Zhao Dianju has a way, and Guo Taijian resigns; Yongxing, Stuart Huang Qiong BiZhao, not; Friends advised him to call, but declined politely, determined to "swim to death" and remain indifferent for life. To those who advised him to pursue his career and pay attention to his career, he often said: "I watch the sky at night and the people at day, knowing that the sky is gone, which is beyond human resources." Geng Jie, a clean and honest celebrity, Fan Pang, the ruler of Runan, commented on Guo Tai's character as follows: "Concealed but not rebellious, chaste, the son of heaven is not a minister, and the princes are not friends." Song Chong, a celebrity in the same county, said, "Since the Han and Yuan Dynasties, there have been no horses." Guo Tai really has a clear conscience.

On the occasion of Emperor Huan and Emperor Ling, "the disaster of party struggle" broke out, and officials and ministers wantonly framed scholars, causing chaos in the ruling and opposition parties. Guo Tai deeply felt that the world was cold, so he gave lectures behind closed doors, with thousands of disciples. In the second year of Jianning (169), during the second "disaster of party struggle", Emperor Han Ling was held hostage by eunuchs, and more than 100 celebrities such as Mars and Du Mi were killed, migrated and imprisoned, and more than 600 people were arrested. Guo Tai was always "not exaggerating" when he gave lectures in his hometown, which saved him from the party disaster. However, he was extremely sad to hear that many celebrities and gentlemen died in vain. In the early spring of this year, Guo Tai, who was heartbroken, was ill at home. On his deathbed, he said, "I'm afraid the world in the Han Dynasty won't last long." . At the age of 42.

Guo Tai's life was short, but it had a great influence. As soon as the news of his death came out, scholars from all over the world flocked to him, and his undertaker reached more than a thousand people. Like-minded people erected a monument for it, and Cai Yong, a famous writer and calligrapher in China, wrote an inscription personally. Afterwards, Cai Yong said, "I have written many inscriptions for people all my life, but most of them are empty words. Only Guo Youdao's inscription is worthy of the name, and I am not ashamed. " This alone shows that the world admires Cathay Pacific.
