Is it necessary to hire a feng shui master?

A friend moved the grave for his parents and invited a "Mr. Feng Shui", and we all went to "pay tribute".

I asked him, "Do you believe what you said?"

He said, "Whether I believe it or not is not the key. The key is to let the host feel a little comfort. "

I said, "Some people believe it, others don't. Say superstitious things to superstitious people. For unbelievers, you can say that this is just a custom and harmless. Wouldn't your business be much better? "

He said, "Thank you, you have helped me a lot!" " I will do this in the future. "

When he left, he took out a "hard jade seal" from the gift money he received and expressed his gratitude.

It seems that Feng Shui theory is purely "pulling the calf"!
