Why did you put several buckets of water in front of the Japanese house?

Some people say this is to collect money.

We all know that Japanese culture is handed down from the Han culture in China. In the dissemination of culture, of course, it will also spread Feng Shui culture. In feng shui culture, two bowls or buckets of water are placed on both sides of the gate, which means gathering water to seek wealth.

The second argument is that this method can prevent wild cats.

It is well known that Japanese love cats, but this does not mean that there are no wild cats. Cats and buckets are completely unrelated things, but why use buckets to prevent cats? Many people think that the reflection of water at night will make cats have slight hallucinations, hallucinations and even escape.

The third argument is that in ancient China, a bucket of water was put in front of the house, and it could be handled in time when it was taken. But now, with the existence of fire fighting tools such as fire extinguishers, this statement is not valid.

According to the Japanese saying, in addition to slowly putting buckets on both sides of the door, trees will be placed. Do you know why? Is it the same as putting a bucket?
