在商周时代,人们一般用青铜制作礼器,同时也有用玉来制作礼器的。礼器是当时国家举行祭祀仪式时的重要器具,是礼仪上必须用到的东西,用玉制作和用青铜制作,性质是一样的。夏、商、周三代都以铜器为国之瑰宝,但周代把玉看得比铜还贵重。按照周代的礼制,在祭祀时,都要用玉器,宴会时必须要用铜器,由此可以得出玉比铜更加重要的结论。 In the Shang and Zhou dynasties, people used bronze to make rituals, but they also used jade to make rituals. The ceremonial instrument was an important instrument at the time of the ceremonial ritual held in the country. It was a thing that must be used in ceremonial ceremonies. It was made of jade and made of bronze, the nature of which was the same. Xia, Shang and Shang dynasties all took the copper as the country’s treasures, but the Zhou dynasty saw the jade as precious as copper. According to the rituals of the Zhou dynasty, jades were used for ritual sacrifices, and bronze instruments were necessary for banquets. From this we can conclude that jade is more important than copper.
