How many feng shui fish paintings should be made in the house?

The ancient literati liked to make pictures of swimming fish, and they were all titled "Jiuru". What is Jiuru? According to ancient books, there is a saying in the Book of Songs: "The heaven protects you, so that everything will not fail to rise. It is like a mountain, a hill, or a tomb, or a river. It is like the direction of a river. It is like the moon's perseverance, and it is like the sun's rise. Just like the longevity of Nanshan, it will never collapse, just like the luxuriance of pines and cypresses, it will never fail.” There are nine "ru" characters in this poem, and they are all auspicious words. Because "ru" has the same sound as fish, many people draw nine fishes and title them "Jiuru" as an auspicious hanging picture. It can be seen from the above that the optimal number is nine.

Nine fish picture, a picture with nine live fish. "Nine" means longevity, and fish means everything goes well, which means having more than enough every year.
