Cactus should not be placed in the east in the office, because the east is the earthquake palace, which represents the motivation and potential of a person's career development. If cactus is placed in the east, it means that there are many thorns on the way forward, which is not conducive to the development of your own career.
Cactus is suitable for the left. Putting it on the left can prevent villains from being right and wrong and enhance their resistance. If you put it on the right, it will lead to quarrels and conflicts between colleagues, which is not conducive to interpersonal relationships.
