EARLY on the morning of August 21,15-yearold Relie Youcong and his grandparents set out to harvest black tartary buckwheat,a type of staple grain for ethnic Yi people.In less than 10 days,the ethnic Yi boy would return to school,and he planned to help his family harvest the grain they planted on the hillside before his leaving.In fact,in order to finish the task as early as possible,the family traveled back to their former home in mountainous Sanhe Village in Liangshan Yi Autonomous Prefecture in southwest China’s Sichuan Province the night before.To them,the trek is worthwhile.“We Yi people have deep affection for the earth.Buckwheat planting is our most important tradition that should be carried forward,”said Relie Youcong,whose family now has risen above poverty after they resettled in a residential community.
