故宫铜大缸又称“吉祥缸”，清朝时期规定为了防止“吉祥缸”内存水的干涸，内廷“吉祥缸”每日由关防衙门内管领率领苏拉（满语，指宫中的差役）近内添水；外朝“吉祥缸”，每日由宫中机桶处苏拉将缸水添足。总管内务府派司员4人负责管理，每5天检查一次缸内的储水情况。

The bronze vat of the imperial palace is also called "auspicious VAT". During the Qing Dynasty, in order to prevent the water from drying up, the "auspicious VAT" of the inner court was led by the leader in the Guanfang Yamen to fill the water in the near inner part of Sula (Manchu, referring to the errand in the palace); the "auspicious VAT" of the outer court was filled by Sula at the machine barrel of the palace every day. The office of internal affairs of the general manager shall assign 4 persons to be responsible for the management and check the water storage in the cylinder every 5 days.
