假如你是李明，你所在的小区要建一个新超市，请根据下列要点，给设计师史密斯写一封建议信，建议他在设计

Dear Smith
Since you are the architecture of our neighborhood's new supermarket, there are several suggestions i would like to offer. Our neighborhood is like a big family and handicapped people in this family deserve more care from us.
First of all, handicapped people need wheel chair to help them going out, therefore the width of the pathway should be wide enough to allow passing a wheel chair. Second, in order to make grabbing goods convinient for handicapped people, the altitude of the shelves should not be too high. Moreover, the position of the elevator should be easy enough for handicapped people to reach.
Everyone in this neighborhood will be glad for your consideration, and our neighborhood will become more harmonious because of the convinience.
Sincerely
Li Ming
