Bi Jingwei, a professor at the School of History and Culture of Shaanxi Normal University, recently accepted an exclusive interview with China News Service's "East-West Question" Bi Jingwei: Around 2000 BC, China entered the Bronze Age. By the late Shang Dynasty, bronze casting technology continued to improve, and the first peak of China's bronze civilization arrived.

After the middle of the Western Zhou Dynasty, the use of bronzes gradually became secular. The most popular patterns on bronzes were animal face patterns, Kui dragon patterns and bird patterns.
