Will hand-painted mouse in room decoration affect Feng Shui?

That depends on the animal sign of the people who live in this house. If the zodiac is a horse, then the mouse and the horse commit six reds; If the zodiac is a sheep, then rats and sheep are mutually harmful; If the zodiac is a rabbit, then the mouse and the rabbit punish each other. Therefore, people who belong to horses, sheep and rabbits can't have pictures of mice in the decoration, otherwise it is easy for the owner to be a villain and talk. If the owners of the house are tigers, horses and dogs, the pictures of mice in the decoration are easy to cause trouble. Other animals will not conflict with mice.
