古时候人们称大缸为门海，从字面上不难理解，铜大缸门海即是门前之大海。人们认为，荷花铜大缸，铜大缸门前有了大海就不会发生火灾了，因此，大缸又被称作“吉祥缸”“太平缸”。在清代，宫中的铜缸是由内务府统一管理的。每天一早，铜大缸，内务府官员便命杂役从井内汲水，寿字铜大缸，一担一担的把所有大缸灌满，以备防火之用。

In ancient times, people called Dagang the sea of the gate, which is not difficult to understand literally. The sea of the gate of the copper Dagang is the sea in front of the gate. People think that if there is a sea in front of the big copper VAT, there will be no fire. Therefore, the big VAT is also known as "auspicious VAT" and "Taiping VAT". In the Qing Dynasty, the copper tanks in the palace were under the unified management of the Ministry of internal affairs. Every morning, the officials of the interior government ordered the workers to draw water from the well. The Shouzi copper VAT was filled with all the vats for fire prevention.
