[PH7.0] Consumer should make choice, but not list.

Ordinary consumers don't know what they really need. What they usually "want" is not what they really need. Consumer's decisions are usually not objective, and easily affected by the things which surround them like advertisement, fashion or words from somebody else. So, let the professionals do their job. Consumer should only need to make choice from the suggestions made by professionals, but not try to be a professional to make a list by themselves for their further choice.
