青铜作品有不均匀点状铜锈的情形产生,形成原因通常是青铜作品在环境中受溼度和氧气及二氧化碳的影响形成表面绿色的〝碱性碳酸铜〞，此生成物能防止铜材继续锈蚀，属於无害锈，并无大碍，有些艺术家或收藏家喜欢铜大缸雕塑生成铜绿的质感会刻意保留，但如果您介意这些铜绿生长有碍观赏的话，建议还是交由专业人员来做保养，因为不慎的处理往往会造成作品的伤害。

Bronze works have uneven spot-shaped copper rust, which is usually caused by the influence of humidity, oxygen and carbon dioxide in the environment to form a green "alkaline copper carbonate" on the surface of bronze works. This product can prevent the copper materials from further rusting, which is harmless to rust and not harmful. Some artists or collectors like that the texture of copper produced by large cylinder sculptures will be deliberately preserved, but If you are concerned that the growth of these bronzes hinders the viewing, it is recommended to leave it to the professional for maintenance, because careless handling will often cause damage to the works.

在皇宫里，根据不同的地点也会安置不同的铜大缸雕塑来作为装饰，作为紫禁城中最重要的中轴线，从太和殿、中和殿、保和殿到乾清宫这一条直线上，均匀的将18口鎏金的吉祥缸分布其中，错落有致。至于为什么要将鎏金的铜大缸雕塑摆放在这些位置，那是因为这些位于中轴线上的宫殿是皇宫中体量大的建筑，而鎏金的铜大缸雕塑也是所有门海中蓄水量大的，所以为了大限度的保证灭火用水的充足，自然要将这些大号的吉祥缸摆放在这条中轴线上，当然除了这个使用价值以外，将铜大缸雕塑通体鎏金，并且铸造上庄重威严的兽头铜环，也给更能显示出皇帝的富有和国家的气派。

In the Imperial Palace, according to different places, there will also be different bronze large cylinder sculptures to decorate. As the most important central axis in the Forbidden City, from Taihe hall, Zhonghe hall, Baohe hall to Qianqing palace, 18 gilded auspicious cylinders will be evenly distributed among them, which will cause mistakes. As for the reason why gold-plated copper cylinder sculptures should be placed in these positions, it is because these palaces on the central axis are large buildings in the Imperial Palace, and the gold-plated copper cylinder sculptures also have large water storage in all the sea gates, so in order to ensure sufficient fire fighting water, naturally these large auspicious cylinders should be placed on this central axis, except for this In addition to the use value, the whole body of the copper cylinder sculpture is gilded, and the beast head copper ring of Shangzhuang is cast, which also shows the wealth of the emperor and the style of the country.
