Is cactus feng shui balcony good?

Cactus is best placed on the balcony, followed by the office and bedroom.

Put it in the office to prevent villains and increase self-defense ability. It is often used to ward off evil spirits, but I don't know that while dissolving each other's evil spirits, it also causes unnecessary anti-evil spirits to myself. If there are children or old people at home, it is easy to have a little influence on them.

The prickly cactus is not suitable for the bedroom, otherwise it will cause disputes.
