Feng shui problem of flagpole

Hello, why do some companies and factories like to get three flagpoles in front instead of one or two, because they all pay attention to feng shui, and three flagpoles represent three incense sticks. Flagpole heights are generally divided into 14m, 16m and 18m. The three flagpoles are different in height, the main flagpole (raising the national flag) 16m- 18m, and the other two flagpoles are 200mm lower than the main flagpole, one of which is the flag in charge of the enterprise bureau and the other is the flag of the company. It has no effect on you. Rest assured.
