The symbols of China's splendid ancient culture mainly include China's four great inventions, astronomical calendars, achievements in architecture, medicine and mathematics, and famous scientific and technological works in ancient China. Shang culture, Qin and Han culture, Sui and Tang culture and Song and Yuan culture are typical examples of China's ancient scientific and technological culture making great contributions to the world. Shang has a unique bronze manufacturing art and an advanced calendar. The outstanding performance of the Qin and Han dynasties was that Chinese civilization began to move towards the west and the world, including silk, smelting and casting, water conservancy technology and so on, and spread to Central Asia, Rome and Europe. The culture of Sui and Tang Dynasties is profound, comprehensive and brilliant, and has made remarkable achievements in almost all fields. Due to the unprecedented prosperity of Sino-foreign exchanges in the Tang Dynasty, the "Chinese cultural circle" recognized by world scholars not only influenced the development of Asian civilization, but also promoted the progress of western and even world civilization. Song and Yuan cultures developed on the basis of Sui and Tang cultures, and the spread of printing, compass and fire technology played a great role in the changes of the whole world.
