VIETNAMESE FARMERS

Vietnam is an agricultural country and about 67% of Vietnamese people live in the rural areas. Both men and women work on the fields. Rural women in Vietnam typically do hard outdoor physical labor, which keeps them physically fit and strong. Everyday, they wake up early to get started on their work, normally before the sun comes up. The fields are near their houses, so they often walk to the field. The entire family helps out during planting and harvest. Each family member has certain tasks to do. Men do heavy labor like plowing and digging. Women work around the house, and help with the harvest,planning and weeding. The elderly do light labor. Children, if not going to school, will help the house chores. Girls clean, cook, and work in the vegetable garden; while boys carry water, and help the men in the field. In the countryside, almost every house has agarden to grow vegetables, fruits for family demand or selling for more incomes. Besides growing vegetables, they also keep cattle, pigs and poultry. The day ends up with a family meal together. It’s a great time for all family members to share their stories and get closer to each other.
