Should feng shui master look after the house before decoration?

Please have a look at Feng Shui before building a house. After building the house, there is no place to put money at home. Please have a look at Feng Shui, otherwise there is no need to look again. Just ask Mr. Feng Shui to look after the house before building it. After that, it is reasonable to ask Mr. Feng Shui to read it again. Otherwise, don't read it again. The more you read it, the more problematic it is.
