As we all known, the disabled are also important members of our society. Unfortunate, they can not do everything like another healthy people because of their disabilities. We need help from others. As a healthy people, we should show them our sympathy (同情)and help them. We should not make funny of them or ignore them. Just accept them for who they were, and help them adjust to the surrounding. When they fail, we can help them in many way, like saying “never mind” to them, giving them encouragement, or help them face the next challenge. In my view, helping the disabled is the duty of everyone rather than only the government.
