BEIJING, July 20 -- China's Internet users have selected 10 individuals and groups of people as grassroots heroes, or China's "Good Samaritans," for the second quarter of 2015.

The winners were announced on Monday following votes by hundreds of thousands of netizens since July 1, according to an announcement by the event's initiator and sponsor, Xinhua News Agency.

They include Liu Zheng, who has spent more than 10 years on treatment and prevention of AIDS. She set up a database on AIDS and provided counselling to high risk groups and infected people, and was dubbed as "Steel Rose at the anti-AIDS battlefront."

The winners also include Guan Dong, the diver who gave away his apparatus when saving two survivors of the cruise ship Eastern Star which capsized on the Yangtze River on June 1, and Huang Shenghong, a farmer who spent nearly all his savings on planting trees for almost 20 years.

The Public Security Bureau of Jilin City in northeast China's Jilin Province was among the winners. Policemen there helped an eight-year-old child with leukemia fulfill his dream of becoming a policeman.

The online vote, held since 2010, is conducted quarterly to promote ordinary people's deeds and improve moral awareness.
