According to ancient records, there is a cloud in the Book of Songs: "Heaven will protect you from prosperity, such as hills, hills and rivers, so that you will not grow." If the moon remains unchanged, if the sun rises, if Nanshan lives long, it will not collapse, if pine and cypress flourish, it will never fail. "。 This poem has nine words "Ru", all of which are auspicious words. Because it is homophonic with fish, many people draw nine fish as auspicious pictures with the theme of "Nine Rus". From the above, the best number is nine.
Nine fish pictures, with nine live fish pictures on them. "Nine" means a long time, fish means everything goes well, and it means more than one year.
