     Wong Fuk-wing (黄福荣), a Hong Kong volunteer (志愿者) at an orphanage (孤儿院) in Yushu, was
killed in the earthquake when he was trying to save others on April 14, 2010.
     Wong managed to run safely out of the building with some children when the first quake happened at
7:50 am on April 14, but he went back inside to rescue three other children and three teachers inside,
although he knew the danger of aftershocks (余震).
     At 10 am, all the children and one of the teachers were saved. However, Wong was buried under the
fallen building and died. The other two teachers were still waiting to be rescued.
     46-year-old Wong was a truck driver, who often said he could only give his efforts to charity (慈善)
instead of money, as he did not earn a lot. His tragic (悲剧的) end touched the hearts of many people both
in Hong Kong and on the mainland.
     Wong began volunteering in 2002. In 2003, Wong was told by the doctor he got serious illness, which
gave him a great blow. However, the illness did not deter the warm-hearted man. When the earthquake
struck Wenchuan is Sichuan Province in 2008, Wong rushed to the disaster area of Shifang to offer his
help though his family did not want him to go.
     In fact, Qinghai is a place Wong had often visited since 2006. As a volunteer, he gave out medicine and
clothing to the orphanage there. No one could expect that Wong would die helping others.
     Hong Kong Chief Secretary Henry Tang Ying-yen said he had "the highest respect" for the hero who
gave his life for others. "What he did has shown the Hong Kong spirit." The citizens of Hong Kong called
him "the pride of Hong Kong's people" and people on the mainland have also praised him as "a true hero".
