I found it great when I visited Shanghai World Expo during National Day vacation.There are lots of
things I think to be creative and I really like them.However,I've seen some bad behavior there.For example,some healthy persons pretended to be handicapped to get the barrier free access.And some healthy people get in through the barrier free access by pushing one wheelchair together.I think it's bad and it did harm to the advantage of the disabled.My suggestion is as follow,
1,Intensify the examination of the tourists
2,Enhance the tourists'consciousness of respecting the disabled.
I sincerely hope Shanghai World Expo would be better and better
