Mr. Feng Shui said that putting white ash on the east side of the grave is good for fortune? Is it possible? Why didn't Mr. Feng Shui do it himself and put white ash on it? There is a great chance of making a fortune. Mr. Feng Shui doesn't want it himself, let others want it? Maybe Mr. Feng Shui has made a fortune, and there is no place to put it, so that others can make some money. I don't know what to say.
