Will you put two fake fish at the door?

I'm not sure about fake fish, but I heard that hanging pictures is good. There are three fish and nine fish. Carp is said to be prosperous wealth, and it also means to have more than one year. Taoism says: "One life is two, two lives are three, and three gives birth to everything". Three carp means endless stream and endless life. In geomantic omen, water is wealth, and such works are often called "prosperous wealth maps", which means good luck, wealth and well-being.
