早在三千多年前,我们的祖先就懂得贮冰和用冰了。《诗经·幽风》中有云“凿冰冲冲,纳于凌阴”,意思是把江河中的冰凿出来,藏在冰库“凌阴”之中备夏日之用。周朝并设有专门的机构掌管冰室,称主管人为“凌人”,为天官之属,凌人以下等级森严,有“下士”、“府”、“史”、“屠”、“徒”等级别。 秦时专门建造了一座水晶宫,宫中设有冰库,夏季炎热,以冰块降温,成为王公贵族消暑之所。汉代史书记载未央宫起火,也把冰库被烧毁之事列入,亦可见当时对冰的珍视。三国曹操在魏地大建冰库,他在赏赐有功之人时,常用冰作为赐品,而功臣们亦宁得一百斤冰,胜得一百斤金,当然这种“金”不是现时所指的黄金,而是黄铜,但其价值亦是不菲。由此可知冰之难得与可贵。
As early as three thousand years ago, our ancestors knew how to store ice and use ice. There is a cloud in the Book of Songs Youyou, which is “chiselled and covered with ice in Lingyin,” meaning that the ice in the river is cut out and hidden in the ice bank “Lingyin” for summer use. Zhou Dynasty and a specialized agency in charge of ice room, said the charge was “Lingren”, is the official of the gentry, Lingren the following hierarchy, “Corporal”, “House”, “history”, “Tu” and “ Only ”level. Qin built a special Crystal Palace, the palace has a cold storage, hot summer, with ice to cool, become the nobility cool summer place. The history books in the Han Dynasty recorded that the Central Government Palace was not on fire. It also included incineration of the ice bank. At that time, it also showed the value of ice. Cao Cao in the Three Kingdoms built a large ice bank. He rewarded the meritorious people with ice as a gift, and the coworkers also deserved a hundred pounds of ice to win a hundred jin of gold. Of course, this “gold” is not the present The gold it refers to is brass, but its value is also high. This shows that the ice rare and valuable.
