Introduction to the Rectangular Bronze Mirror with Dragon Pattern: The "Rectangular Bronze Mirror with Dragon Pattern" from the Tomb of King Qi is an unearthed cultural relic from the Western Han Dynasty. The mirror is 115.1 cm long, 57.5 cm wide and weighs 56.5 kg. There are five ring-shaped string buttons on the back, and two buttons are cast on the two short sides. Each ring button is decorated with persimmon stem-shaped patterns. The back is also decorated with a tangled pattern of Kui dragons, which are curled and interlaced freely. This large bronze mirror was probably supported by pillars and seats, and the buttons on the back and sides of the mirror were probably used to fix it to the pillars and seats. It was unearthed in 1980 from the burial pit No. 5 in the south ancient tomb in Wotuo Village, Dawu Commune, Zibo, Shandong Province.
