Clark Tang Clark Tang with his father, Chea Pen, on Clark’s first trip back to Cambodia in 2001. Clark had not seen his father since 1979 when he and his grandmother escaped to Thailand. His father was a tailor before the war and the Khmer Rouge had treated him relatively well. Fearing the trip was too dangerous, his mother and father chose to stay in Cambodia rather than make the trip to the refugee camps in Thailand. Clark sponsored his parents to the U.S. and is currently taking care of them. Location: Banteay Srey temple, Siem Reap, Cambodia.
