Bronze Dragon, before the Ming Dynasty, 16cm in height and 35cm in length, unearthed from the noble tombs or cellars from the Han Dynasty to the Tang Dynasty and later collected privately. Made of bronze with natural red spot and green rust on the surface. Cast by the lost-wax method, the dragon is curled in an "S" shape with a vigorous shape, and the scales and manes are depicted clearly, reflecting the powerful style of the bronze craftsmanship of the Han Dynasty. The bronze dragon of the Han Dynasty from the Han Dynasty to the Tang Dynasty (206 BC–907 AD) is rare in existence, an important relic of the ancient dragon culture, with extremely high historical and artistic values, and is cherished by museums and senior collectors.
