What does it mean to sit in a feng shui fish tank?

Therefore, if you put the fish tank behind the sofa and the family sits there every day, it will be unreliable and affect the stability of the house. If the fish tank is placed next to the sofa, the number of fish should be coordinated with the five elements of the head of the household: how many fish are raised in the fish tank is in line with Feng Shui, mainly according to the divination and five elements of the head of the household.
