The main purpose of Preface to the Inscription of Jinci is to summarize the historical relics of Tang Shuyu's founding through Zhou Zong's politics, so as to carry forward the martial arts of the Tang Dynasty and consolidate the political power. Its general content can be divided into four parts:
First of all, it is proposed that "prospering the country and building the country" must be close to the nobility as a supplement; "Guangxi society" should also give fiefs to master the military and political essence. "No relatives, no foundation, no virtue and no enlightenment." It is believed that without relatives, the country cannot be consolidated, and without benevolent government, the people cannot support and love it. The Zhou Dynasty is the oldest dynasty in the history of China, with 37 emperors who ruled for more than 800 years. Li Shimin believed that the enfeoffment system of the Zhou Dynasty was the fundamental guarantee for the country's long-term stability, and vigorously promoted it. Therefore, The Preface to Jinci Inscription has become a precious historical material reflecting Li Shimin's political thought.
Second, Li Shimin praised Tang Shuyu's achievements, saying that he was a pillar and the ancestor of the State of Jin. Based on the heroic spirit of "taking Liuhe as home" and the gorgeous style of "respecting benevolence and caring for righteousness", this paper makes a personalized evaluation of the landscape of Jinci, which is "benevolent, compassionate and generous".
Thirdly, it exposed the brutal rule of Emperor Yang Di, so that the man of God became angry and made waves everywhere. His father, Li Yuan, obeyed the people and got support, thus unifying China.
Finally, Li Shimin wrote, "Although the seal script is subject to the map, it shows its fate; However, often the red leaves really depend on magic. " It is believed that the Tang Dynasty regime belongs to the destiny and the will of the people, and prosperity is indeed magical. To this end, he said, "The sun and the moon are poor, and there is no shortage of English sounds." Express Tang Shuyu's demeanor with the exaggerated tone of "extreme heaven and earth, great power drops". Finally, I wish "thousands of generations and thousands of years, fragrance will last forever", in order to make the Tang room permanent.
After 1300 years, the Tang stele has been eroded, with blurred traces, distorted characters and damaged lower parts. Nearly 200 characters are unrecognizable. Although the Qing Dynasty re-carved a new monument in the thirty-five years of Qianlong, the handwriting was dull and the shape was gone, completely losing the charm of the original monument. Qingshitang specially collected dozens of old rubbings in the late Ming Dynasty, and after painstaking repair, they became the most complete and clear rubbings.
