Singer-songwriter Han Hong launched her Charity Action three years ago with a simple desire to help the needy. Since then, the group has helped 100 or so volunteers to visit victims of disasters in Sichuan province's Wenchuan and Zhouqu, Gansu province.

Her latest move will see about 100 health experts travel 1,000 km from Qamdo in the Tibetan autonomous region to the regional capital Lhasa to visit children and elderly people.

With funds of 6 million yuan ($940,000), the volunteers will help improve medical conditions, such as establishing a center for eyesight recovery, and offer free health services.
