Is the blue shark a Feng Shui fish?

Nowadays, the word Feng Shui has been ruined beyond recognition by those unscrupulous businessmen and mediocre Feng Shui masters. Those who sell fish call it Feng Shui fish, and those who sell flowers and trees call it Feng Shui flowers and trees. I estimate that things like Feng Shui toilets and Feng Shui toilet paper will appear in the future. It is sad to see the precious wealth passed down by our ancestors being wasted.
