(VOVworld) - Harvest time is probably the most beautiful season in the northwestern Vietnam with many vast yellow terraced fields. These fields, which were created by many generations of ethnic minority groups like the Ha Nhi, H'Mong and Dao, have existed for hundreds of years in Vietnam. Visitors often flock to the region during September and October to capture this most beautiful moment of the year with their own eyes. VOV introduces some photos taken in Mu Cang Chai in the northwestern Vietnam, during harvest time, by Nguyen Anh Tuan.
