In ancient times, buildings were generally made of wood. Wood has a low ignition point and is easy to ignite, so ancient buildings can easily be burned down by a fire. In ancient times, there were no faucets. Once a building caught fire, if there was not enough water to put it out in time, the house would be destroyed. Therefore, rich people put water tanks in their yards to extinguish fires in time. Of course, putting water tanks in their yards can also have a certain decorative effect. Ancient people who believed in Feng Shui believed that placing water tanks in their yards could attract wealth.
People in ancient times loved Feng Shui and liked to add some decorations to their empty yards. They believe that placing a water tank in the yard can attract wealth, and some aquatic plants, such as lotus leaves, or goldfish will be placed in these water tanks, making the water tanks very beautiful.
The ancients knew that by putting goldfish into the water tank, they could know whether the water quality in the tank had changed and whether the water tank contained toxins. Because if the water tank is kept for a long time, the plankton, aquatic plants, and bacteria inside will multiply and produce toxins. Once people drink it, they will be poisoned or sick, so goldfish should be placed in the water tank.
In ancient times, droughts often occurred, and people could not find water to drink, so they could only put some water tanks in the yard to store water, so that they would not be so afraid of droughts. Once there is no water to drink, you can heat the water in the water tank and boil it for drinking, which is very convenient.
In ancient times, there were no faucets, and getting water was a very troublesome thing. People put water in the water tank in advance and can use it when they want.
One of the biggest uses of water tanks is to extinguish fires. Ancient buildings were basically made of wood. Houses with wooden structures were easy to catch fire. There were no water guns or pipes at that time. You had to fetch water yourself to put out the fire. However, fetching water was inconvenient, so the ancients put several water tanks in the yard in advance. , once a fire breaks out, you can get water and put out the fire in time.
