古人的智慧是无穷的，他们在大缸里设置了专门的“铁屉”可以贮存炭火，而且每口大缸下面还可以放置木炭生火，同时宫人们还体贴的给大缸们都“穿上”棉衣，这样来防止缸里的水结冰，就为了伺候这些大缸，内务处还专门设置了“熟火处”。

The wisdom of the ancients is infinite. They set up a special "iron drawer" in the big tank to store carbon fire, and under each big tank, charcoal can be placed to make a fire.

In order to serve these big tanks, the internal affairs office also set up a special "fire ripening place".
