Business is not good. Is it useless to ask Mr. Feng Shui to set up Feng Shui?

I don't think business is doing well. Please ask Mr. Feng Shui to put on Feng Shui. It's no use trying to do business well! This is superstition! We should sum up our experience, find out the reasons for bad business and improve! If Mr. Feng Shui can make his business prosperous by putting on Feng Shui, why doesn't Mr. Feng Shui put on Feng Shui for himself? Do big business! If it was a spirit, he wouldn't have to give feng shui to others!
