The paper discusses ZHENG Xuan's interpretations of Zhouyi, an ancient Chinese text. It shows that ZHENG Xuan's Yi studies consider both images and meanings, not just numbers. Previous scholars thought he focused only on numbers, but that's not true. ZHENG Xuan's approach to interpreting Zhouyi involves connecting it with the Yao chen system from the Han dynasty. While his ideas are insightful, they don't completely match the original meaning of Zhouyi.
