Editor's note: Monday marks White Cane Safety Day, an international event designated by the World Blind Union to help the public better understand blindness and visual handicap.

China has over 17 million blind and visually-impaired people. Most are restricted to home due to lack of reasonable access to public places. In such a situation the guide dog, "bright angel" can assist sight-impaired people.
