Feng shui fish-good luck for a long time:
There are white spots or yellow stripes on the black background, commonly known as "blocking koi fish". Black has the function of "blocking evil spirits" in Feng Shui, and most people use it to face evil spirits, so as to block evil spirits. Snake is the most prosperous zodiac sign in career and fame, and it is also the most suffocating zodiac sign. This kind of "warding off evil spirits from koi fish" is the best way to ward off evil spirits, which makes up for its kindness and good fortune.
