First of all, literary inquisition was almost unique to the Manchus. Even Mongolia did not prohibit the survivors of the Southern Song Dynasty from writing articles in memory of their homeland. Most other dynasties did not imprison people based on their writing. In the end, Su Shi's Wutai poem case was just demoted and released. His brothers could still be high-ranking officials like Yushi Zhongcheng.
Then, the imperial examination system was gradually established and improved in the Tang Dynasty. In order to ensure the fairness of the imperial examination, the central government not only revised the unified text of Confucian classics, but also enriched the content of the imperial examination. A large number of people who studied various schools of thought had the opportunity to enter the government. However, in the later dynasties of Gaozongwu, in order to consolidate the power of the central government and suppress the privileges of the military aristocracy, the focus of the imperial examinations gradually shifted to the Jinshi subject, with emphasis on the selection of poetry ability. Gradually, the official class became completely bureaucratic and civilized.
The power of the Tang Dynasty is inseparable from its own openness, tolerance and progressive cultural genes. The Tang Dynasty originated from the Northern Dynasties and had a large amount of influence from the Xianbei tribe culture. Secondly, Han culture was integrated into the culture of the Northern Dynasties through Hou Jing's Rebellion and the annihilation of Northern Liang. The Tang Dynasty was not an inward-looking mainland empire when it was founded. The war against the Turks can be called the war of founding the country. The war from Emperor Sui Yang to Taizong and then to Gaozong to annihilate Goguryeo was a great conquest. Make a list: Heiji Changzhi (Baekje), Li Guangbi (Khitan), Ge Shuhan (Turkic), Gao Xianzhi (Goguryeo), Chao Heng (Japan), Fumeng Lingcha (Qiang), Ashina Sheer ( Turks), Zhilosisi Li (Turks), Husero (Turks), Ashina Mishe (Turks), Puguhuaien (Tiele). Among the prime ministers of the Tang Dynasty, 29 were foreigners. Among the ministers and generals, the proportion of various ethnic groups is even more astonishing.
It has an imperial examination system that breaks down class barriers and does not define personal development based on racial identity. The selection of talents in the prosperous Tang Dynasty ensured that all the true heroes of the world would be selected.
When Li Linfu arrived, he corrupted the imperial examinations with one hand and suppressed the Han generals with the other. From then on, the world was troubled.
