The signing of the Indo-China ceasefire agreement in Geneva on July 21, 1954 resulted in a divided Vietnam. Thousands of overseas Chinese in North Vietnam, unwilling to stay behind the Iron Curtain, evacuated their homes and went to South Vietnam.　　In response to the wide-spread campaign for their relief, the Directorate General of Posts issued a set of stamps on which a surtax was collected as relief funds.　　The stamp design is a picture of young and old refugees fleeing over a pontoon bridge constructed by their mother country, from a war-stricken area to an area of freedom.
