What do you mean by seven red fish and six black fish in a fish tank in geomantic omen?
Specifically, is this fish tank you see a master? Or did someone else mess it up and let you guess?
In geomantic omen, 6 and 7 are all gold, and together they are 6 and 7 swords. Not good!
It is estimated that the person who decorated this pattern took the meaning of fire, water and auspicious according to the principle of 16 combined with water and 27 combined with fire, but the number of 1 and 2 was too small, so 6 and 7 were chosen. But I don't quite agree with this practice, because solitude will become the sword above.
Let me tell you a simple fish farming rule:
People who divine water with five elements can keep a goldfish or a goldfish from Vulpix.
People with five elements of fire can keep two or seven goldfish.
People who belong to the five elements of numerology divination can keep three-tailed or eight-tailed goldfish.
Those who belong to the Five Elements Divination can keep four-tailed or Kyubi no Youko goldfish.
People who belong to the five elements can raise five-tailed or ten tail goldfish.
If the fish tank is large and the numbers on it are too small, the two groups of numbers should be combined, but the two groups of numbers should be separated by light and dark colors.
People who belong to the five elements of numerology and water can raise a light-colored fish and a dark-colored fish from Vulpix. These two fish are seven tails.
People with five elements belonging to fire can raise two light-colored fish and seven dark-colored fish, which is called Kyubi no Youko.
People who belong to the five elements of numerology divination can keep three light-colored fish, eight dark-colored fish and eleven fish.
People who belong to the five elements of numerology divination can raise four light-colored fish and Kyubi no Youko dark-colored fish, a total of 13 fish.
Those who belong to the five elements of numerology divination can keep five light-colored fish and ten tail dark-colored fish, a total of fifteen.
Note: it is best to choose auspicious day for the first time (the water is full the day before, and it is better to use fresh water the next night). Then put the goldfish down from the bucket and start the air pump, and you're done.
