The political unity of Sui and Tang Dynasties and the prosperity of feudal society and economy laid the foundation for the prosperity of Sui and Tang Dynasties culture. The enlightened cultural policy of the rulers also promoted the prosperity of culture, and the open foreign policy was eclectic, which also made the culture prosperous.

Status: The splendid culture of Sui and Tang Dynasties not only reached the peak in the history of ancient feudal culture in China, but also took the lead in world development.

It has reached a fairly high level in economy, politics, culture, science and technology, art and music. If the development of feudal society in China is compared to a parabola, the Tang Dynasty is undoubtedly the highest point, which can never be reached or surpassed at that time.

China's top scientific and technological achievements in Sui and Tang Dynasties: Zhao Zhouqiao, block printing (printed diamond sutra), Mogao Grottoes, gunpowder;

1. Zhao Zhouqiao:

Zhao Zhouqiao is located on the Weihe River in Zhao County, Hebei Province. It was built in the great cause of the Sui Dynasty (AD 605-6 18), designed and built by the famous craftsman Li Chun, about 1400 years ago. It is the earliest and best preserved ancient open-shouldered stone arch bridge in the world today. This bridge has scientific design, long span, gentle deck, convenient transportation and beautiful shape, which embodies the industriousness and creative wisdom of the ancient working people in China, more than 700 years earlier than in Europe.

2. Block printing:

Printing is one of the four great inventions in ancient China. The earliest printing method was block printing, in which pictures or words were engraved on a flat plate and then printed with ink. The earliest existing printed matter is the remnant of the Diamond Sutra printed by Tang Yizong Xian Tong in the ninth year (868), with a picture on the front and exquisite carving, which is now in the London Museum. Printing, invented in the Tang Dynasty, gradually spread to all parts of the world and made great contributions to world culture.

3. Dunhuang Mogao Grottoes:

Dunhuang Mogao Grottoes is one of the largest art treasures in the world. It is located on the cliff of Mingsha Mountain in Dunhuang, Gansu Province, with more than 1000 caves, in which different expressions of Buddha statues are shaped and magnificent murals are drawn. Among them, the grottoes in Sui and Tang Dynasties accounted for 67/ 10, and the most exquisite Buddha statues and murals were mostly works of this period.

4. The use of gunpowder in the Tang Dynasty:

China was the first country in the world to invent gunpowder. The study of gunpowder began with ancient alchemy. In the books of the mid-Tang Dynasty, there was already a formula for making gunpowder. At the end of the Tang Dynasty, gunpowder began to be used in the military, and the rocket was the earliest gunpowder weapon.
