Taking the "mountain pattern" bronze mirror in the Warring States period as the research object, the paper aims to compare the design sources of the "mountain pattern" in the "mountain pattern" bronze mirror, study the design types, mountain pattern features, combination form changes, ground pattern decoration and usage principles of the "mountain pattern" bronze mirror, and explore the design concept and cultural heritage of the "mountain pattern" bronze mirror.From the perspective of design science, combined with archeology, iconography, history, etc., the changing characteristics and types of the "mountain pattern" bronze mirror, visual form and aesthetics, and use of reflection, etc., and the origin, decoration, practicability and locality of design of the bronze mirror during the Warring States period are analyzed. The design connotation and cultural genes of the pattern are explored. The "mountain pattern" bronze mirror in the Warring States period is innovated in inheritance. It has special design ideas and cultural value at that time. Its "mountain pattern" and pattern combination are rich in visual aesthetics and each has its own characteristics. It has created special morphological symbols in the Chu region. It is also a symbol of Chu culture, belief, and aesthetics. It integrates history, culture, aesthetics, belief, and utility, and represents the new art and new achievements of bronze mirror design in a period of time and region.
