Although there are even numbers, there will be fewer, and in Feng Shui, odd numbers have a better effect on Feng Shui than even numbers, so it is best to raise odd feng shui fish.
In geomantic omen, Yang is double and Yin is single. Feng shui fish are generally cloudy, so when raising feng shui fish, it is naturally best to choose odd numbers. Only an odd number of feng shui fish can match their temperament, thus making the feng shui yin and yang more balanced, so that the feng shui in the house will be more prosperous.
Generally speaking, odd numbers represent yin in yin and yang, and fish itself belongs to yin, so if you choose to raise odd numbers when raising feng shui fish, it will naturally make the feng shui of the house more balanced, because numbers belong to yin and fish belong to yin, which can form a balanced pattern with other items in the room that belong to yang.
The odd number of feng shui fish makes the feng shui yin and yang balanced, and the indoor feng shui atmosphere is generally strong. Moreover, fish and fish tanks themselves have good feng shui functions, such as making money and bringing more unexpected good luck. Moreover, after raising an odd number of feng shui fish at home, the effect in this respect will become better.
