See why feng shui must be charged.
According to the law of cosmic balance, the location and planning of Feng Shui master is a matter that goes against nature, the laws of nature and bears considerable responsibility. If you give away this precious cosmic resource for free, you are sent by heaven. Therefore, the better the geomantic omen, the more the master should contribute. Failure to contribute or not contribute is at the cost of the master's life.
Some people want Feng Shui masters to be complacent without spending money to watch Feng Shui, knowing that there are natural laws in the universe. If you get it, you have to pay, and if you give up, you have to get it. If you get something, you will be punished by the law of cosmic balance.
If we use modern ideas to explain why feng shui masters charge and why masters pay, it is a simple word: intellectual property rights.
Feng Shui master has a code of professional ethics: don't be a villain, don't be a prostitute.
