走过故宫许多遍，我们肯定都看到门口伫立的这些缸，虽然但大部分时候，都是一眼略过。却不知，这样一个简单的设置，却是有大用途————灭火！

After walking through the Forbidden City many times, we must have seen these tanks standing at the gate, although most of the time, they were all ignored. But I don't know, such a simple setting, but it has a great use - fire fighting!

在以前，古时的房子大多是由木头做的，火灾频发，为了能够及时救火，就在门前放置了大缸并时常将水注满。当时，人们称大缸为“门海”。顾名思义，“门海”即是门前之大海。取“门前有了大海就不会再发生火灾”之意，因此，大缸又被称作“吉祥缸”、“太平缸”。“吉祥缸”有铜缸和铁缸两种，，每年到了农历小雪季节，由太监在缸外套上棉套，上加缸盖，下边石座内置炭火，防止冰冻，直到春节后惊蛰时才撤火。

In the past, most ancient houses were made of wood. There were frequent fires. In order to put out the fire in time, large tanks were placed in front of the door and water was often filled. At that time, people called the VAT "Menhai". As the name suggests, "gate sea" is the sea in front of the gate. Take the meaning of "the sea in front of the door will not cause fire again". Therefore, the big tank is also called "auspicious tank" and "Taiping tank". There are two kinds of auspicious tanks, copper and iron. In the light snow season of the lunar calendar, the eunuch puts a cotton sleeve on the cylinder jacket, a cylinder head on the top, and a charcoal fire on the bottom stone base to prevent freezing. The fire is not removed until after the Spring Festival when the insects start.

大缸灭火的作用沿袭了多朝，到明成祖朱棣在故宫初建之时，让设计师将护城河的水引进故宫，成了今天的金水河，解决的故宫用水的问题，也设置了许多大缸。同时，故宫内还掘有水井80余口，除了供宫太监饮用之外，也是为救火之用。

The function of big tanks for fire fighting has been followed for many dynasties. When Zhu Di, the founder of the Ming Dynasty, built the Forbidden City at the beginning, he asked the designers to introduce the water from the moat into the Forbidden City, which has become today's Jinshui River. Many big tanks have been set up to solve the problem of water use in the Forbidden City. At the same time, there are more than 80 wells dug in the Palace Museum, which are not only for the palace eunuchs to drink, but also for fire fighting.
