What are the "upright writers" in history?

In the history of China, after the Song Dynasty, a very strange phenomenon appeared. After becoming an official, all the literati dreamed of getting a posthumous title-Zheng Wen. As the ruler of the emperor, it is not easy to give this posthumous title to others. In history, most of the people who got Zheng Wen, the posthumous title, were admired by the literati at that time. As far as mourning methods are concerned, the word "Wen" has no fixed counterpart, such as Zhang Zhao,, and others, all of which are single words. Wang Dao and posthumous title in the Eastern Jin Dynasty are documents. Throughout the Eastern Jin Dynasty, he was the only one who buried documents. In the Tang Dynasty, Wei Zhi, Lu Xiangxian, Song Jing and others got posthumous title from Wen Zhen. In the Tang Dynasty, it was Zhang posthumous title or the emperor who wrote in person, which ended the courtiers' argument about whether Zhang should be in posthumous title. In the Northern Song Dynasty, it was customary to inherit the Tang Dynasty. In the early years, several ministers, such as Liu Yun and Wang Dan, were all called Wen Zhen. When I arrived in Song Renzong, because Song Renzong's name was Zhao Zhen, in order to avoid it, Wen Zhen was changed to Zheng Wen. When Xia Song was drafted as Wen Zheng, Sima Guang first proposed: "Wen is extremely beautiful and hard to see." Sima Guang thinks that literature is moral erudition, which is Jing's position and the ultimate of literati's morality. After his propaganda, Zheng Wen is considered as the most beautiful person and minister in posthumous title. The emperor refused to give it to others easily. Fan Zhongyan, Sima Guang, Wang Dan, Wang Zeng, Zheng Zhongzhong, Liu, Ni, etc. Wu Cheng, Ye Luchu, Cai and Xu Hengming were posthumous title in Yuan Dynasty. When Li Dongyang, a great scholar in Ming Dynasty, was dying, Yang Yiqing, a great scholar, came to see him. Seeing that Li Dongyang was worried about posthumous title, Yang Yiqing told him to give him a decent posthumous title after his death. Dying Li Dongyang kowtowed to Yang Yiqing in bed. Because Li Yang and his wife have a close personal relationship, someone wrote a poem sarcastically saying, "Zheng Wen has never criticized dorri, but now it is very difficult for Zheng Wen. The wind blows on the plane tree, and others say it is short. " In the Ming Dynasty, posthumous title Zheng Wen was acquired by Fang Xiaoru, Li Dongyang and Xie Qian. Fang Xiaoru was killed because he refused to accept the order of Prince Tsao, that is, the throne, and the axe king came after Zheng Wen. For more than 200 years, there were eight people in the Qing Dynasty, including Tang Bin, Liu Tongxun, Zhu Gui, Cao Zhenyong, Du Shoutian, Zeng Guofan, Li Hongzao and Sun Jianai, in posthumous title and Zheng Wen. However, Cao Zhenyong is not worthy of the name. He is loyal to Nuo Nuo and dedicated to him. So the world has been criticizing his posthumous title. However, Tang Bin ratified it. Liu Tongxun is the direct obituary of Zheng Wen. Zeng Guofan's contribution was indeed great, but the situation in the Qing Dynasty was inspiring. As for Li Hongzao's teacher status, after him, all teachers have the possibility to be teachers. In the next few years, it was a bit like a masterpiece of the last era, which meant that it was not expensive.
