Brief description: Unearthed in 1983 in Bazhong County, Sichuan Province. It is now collected by the Sichuan Provincial Museum and is a national first-class cultural relic. Round shape, plain wide rim, round button, mirror button base with chrysanthemum pattern. The decoration on the back of the mirror can be divided into three circles from the inside to the outside. The inner circle is a Bagua pattern, the middle circle is the twelve zodiac animals, and the outermost circle is a pattern of entangled branches and petals. There is an inscription in regular script in the middle of the Bagua pattern on the inner circle: "Wude Jun Zuo Yuan Luo Zhen Zao". Wude Military Crafts Institute is a handicraft workshop run by the former Shu government. Since this historical stage was relatively short, the bronze mirror is even more precious. It is a valuable cultural relic for studying handicraft workshops during the Five Dynasties and Ten Kingdoms period.
