Rectangular bronze plaques with serrated openwork pattern, which were distributed in the Northern Frontier Zone of China, the Southern Siberia and trans-Baikal areas, were tightly related to Xiongnu ethnic group. From the 2nd century BCE to 1st century CE, the bronze plaques with serrated openwork pattern and griffin figure on the edges underwent an evolution of pattern simplification. The bronze plaques with serrated openwork pattern and concave pear on the edges was popular around the 1st century CE; the bronze plaques with symmetric serrated openwork patterns along edges were popular around the 2nd century CE; the ones of this type of bronze plaques distributed in the Northern Frontier Zone of China had nipple pattern on the obverse, and other two types of bronze belt plaques with openwork patterns evolved from that with serrated openwork pattern also existed in this zone at this period. 展开更多
