Our friendship is made from heaven -- Retired U.S. teacher Ronald Sakolsky on his friendship with China's green hero Yin Yuzhen
Over 20 years ago, Sakolsky donated $5,000 to support Yin's tree-planting efforts. Today, the 50,000+ trees that grew from that donation stand as a living example of friendship between the two peoples.
