In the extensive history of Ancient China, the four dynasties—Zhou, Qin, Han, and Tang—not only created immense material wealth but also witnessed spectacular cultural prosperity. As glorious pinnacles of Chinese cultural achievements, these four eras contributed greatly to the development of human civilization in general, and their economic, political, cultural, and social legacies are still felt in China today. The system of rites and music of the Western Zhou dynasty forms the core of traditional Chinese thought and culture; the various systems established by the Qin dynasty after the unification of ancient China form the basis of China's political civilization for the next two thousand years; the opening of the Silk Road during the Han dynasty made China known to the outside world for the first time as a developed civilization; the golden age of the Tang dynasty was and will always be remembered by the Chinese people as a source of national pride and inspiration to move forward. These four dynasties represent the apogee of ancient Chinese civilization and left behind a great number of historical relics of enormous cultural value, archaeological sites that hold the keys to questions that have puzzled later generations for thousands of years, and an intellectual legacy that we feel obligated to pass on to future generations.
