Li Shimin (65438 +5981October 28th, 65438 +5991October 23rd -65438 July +00, 649), that is, Emperor Taizong (reigned from 626 to 649), was born in Bewutang (.

Shortly after Li Shimin ascended the throne, a new library was built according to the model of Qin Literature Museum, which further reserved world literary talents. Li Shimin knows how to perform people's duties well and employs people according to their abilities, regardless of their origins. Fang Lingxuan and Du Ruhui were used in the early stage, and Sun Chang Wuji, Yang Shidao and Chu Suiliang were used in the later stage. They were all honest people.

Others, such as Li Ji and Jing Li, are also famous for their generation. In addition, Li Shimin also let bygones be bygones, re-used the old headquarters of Wei Zhi and Wang Gui, and handed over Weichi Gong and took away a large number of talents.

Li Shimin regarded Yang Di's refusal to remonstrate with national subjugation as a warning. After he acceded to the throne, he tried his best to speak. He expanded the power of admonishing officials and encouraged ministers to criticize his decision-making and style. Among them, Wei Jin remonstrated more than 200 times and told the court about Chen's fault, which made him embarrassed many times in the early years and unable to step down.

Extended data:

In the seventeenth year of Zhenguan (643), 63-year-old Wei Zhi died of illness, and Li Shimin, Emperor Taizong, was very sad, so he abandoned the five-day pilgrimage. On this basis, the Tang Dynasty posthumously awarded Wei Zhi as the commander-in-chief of Sikong and Xiangzhou, and named him "Wen Zhen".

However, it was not long before Li Shimin, Emperor Taizong, issued a letter to dissolve the engagement of betrothed Princess Hengshan to Wei Shuyu, the eldest son of Wei Zhi, and insulted Wei Zhi who had entered the loess by "knocking down the stone tablet" and "erasing the inscription".

Specifically, two things prompted Emperor Taizong Li Shimin to order the destruction of Wei Zhi's tombstone.

1, the recommended Hou and Du are related to Prince Li Chenggan, that is, the Chu Jun issue in Li Shimin. In the ancient history of China, the heir to the throne was a taboo for the emperor. Once a minister intervenes, there is often no good result. For example, during the Three Kingdoms period, Lu Xun, who made great achievements, was accused by Sun Quan because of the issue of the heir to the throne, and eventually died of anger.

2. As for Li Shimin, Emperor Taizong, due to the stain caused by the change of Xuanwu Gate, he attached great importance to his reputation and wanted to shape the image of a monarch, which was also an important reason why he was able to treat submission modestly. However, Wei Zhi gave the materials of "Advice" to the historian Chu Suiliang before his death, which was suspected of exposing Li Shimin's background. If there is anything negative in the exhortation materials, it is obviously not conducive to the shaping of the image of Emperor Taizong.

Under the influence of these two events, Li Shimin finally lost his temper and ordered the destruction of Wei Zhi's tombstone. However, in 645 AD, after the expedition to Koguryo, Li Shimin, Emperor Taizong, remembered Wei Zhi again and once again set up a monument for Wei Zhi.
