Wei Zheng, character Xuancheng, Julu Quyang people. Wei Zheng was lonely and poor since he was young, but Luo Tuo had great ambitions and did not work for a living, but chose a partial family and became a Taoist monk. He is a good reader and has a lot of knowledge. At the end of the Sui Dynasty, he saw that the world was gradually chaotic, and he especially focused on reading the works of those longitudinal masters in the Spring and Autumn and Warring States. After Li Mi raised his army, he went to surrender. Later, he was caught by Dou Jiande, and because of his talent, he was worshipped as a living quarter. After Jiande was captured, the crown prince Li Jiancheng heard of his name and was introduced as a straight horse, and he respected him very much. Wei Zheng saw that Li Shimin, the king of Qin, was growing in his career, and often advised Li Jiancheng to get rid of this brother early.
After the change of Xuanwu Gate, after Jiancheng was killed, Li Shimin personally tried Wei Zheng, who was captured: "You separated my brother, why?" Wei Zheng replied, "If the crown prince had listened to me earlier, there would be no calamity today." In fact, Li Shimin had long admired Wei Zheng's daimyo, and did not want to kill him at all, and after ascending the throne, he worshipped him as a counselor.
In fact, Prince Li Jiancheng is also a good person, but after he was killed, he completely lost his "right to speak", and the later Emperor Taizong's courtiers will definitely praise Li Shimin and try to belittle Li Jiancheng. Even the "Zizhi Tongjian", which was written with a lot of materials from the "Great Records", has a record that "the eldest son is quite benevolent", and once Li Yuanji wanted to "slash" the king of Qin, Li Shimin, and the eldest son was built and "obstructed". According to the analysis of existing historical materials, Li Jiancheng also had many meritorious achievements when the Tang Dynasty was founded, and he was not a sinister and cunning person at all, and all of his achievements were later erased by Emperor Taizong's Shichen. Although Dazong had great martial arts achievements at the founding of the Tang Dynasty, these are not the inevitable capital to be an emperor, and the concubine who attacked the throne is the right principle of feudal society, if you can fight and kill and become an emperor, it will definitely be a chaotic time. Emperor Taizong must have felt guilty later, as evidenced by his later performance when he participated in the reburial of his brother.
At the beginning of the reign of the Great Emperor, he worked hard to discuss with Wei Zheng in the inner hall many times, and visited the world for gains and losses. Wei Zheng knew everything, said everything, resisted and resisted, and had nothing to hide, he often violated Yan Jinjian, his expression was unwavering, and his deeds were recorded in history. Zhenguan for seven years, entered the title of Duke of Zheng Guo.
In the sixteenth year of Zhenguan, Wei Zheng died of illness at the age of sixty-four, and that night Emperor Taizong Li Shimin dreamed that Wei Zheng was "like a peaceful life". Emperor Taizong gave him the gift of Sikong and Wenzhen for the fifth day of his death.
It is worth mentioning what happened after Wei Zheng's death. Wei Zheng had secretly recommended to Emperor Taizong that Du Zhenglun, a Zhongshu attendant, and Hou Junji, an official Shangshu, had the ability to be prime ministers. After Wei Zheng's death, Du Zhenglun was deposed for his crimes, and Hou Jun was accused of plotting against him, and Li Shimin suspected that this "honest man" was suspected of being private. Later, Emperor Dazong also learned that Wei Zheng had shown the manuscript of Bai Ji's book to Emperor Dazong to the historical official Chu Suiliang, and he was even more displeased, and ordered the cancellation of the marriage contract that had previously promised the princess of Hengshan to Wei Shuyu, Wei Zheng's eldest son.
In any case, the history books say to Wei Zheng about Fei Mei: "The wise do not advise, advise or are not wise." Wisdom is the benefit of the country. Zheng Gong (Wei Zheng) reached the festival, and only Zhou economy. Emperor Taizong used it, and his descendants lived forever. ”
