Family fish farming is considered only for ordinary people to watch. But family fish farming is not only ornamental, but also a hobby and fun for people. 2. It has more important significance in geomantic omen. Fish is the most important animal. More than 90% animals on land are evolved from aquatic animals. So people of insight believe that fish is the earliest ancestor and should be respected and blessed. 3. Fish and water in geomantic omen mean that where there is life, there must be water. If the Tathagata only has life without water, life will not last, and even the sky will die and there will be no more. Therefore, life and water constitute an inseparable whole. 4, water and fish, usually everyone knows that fish can not do without water. And the pronunciation of fish means (fish), so don't look at your home: ah! Your family has fish (surplus)! This kind of induction can increase the induction of auspicious phonology, which is an auspicious omen. 5. The adaptation of family fish farming in Feng Shui can also turn disasters into disasters, that is, turning disasters into blessings. Because fish and water constitute the whole of life, anything unlucky that loses face will run away after seeing all the fish and water, and only the owner can enjoy the life of fish and water at home.
