In agricultural countries like Vietnam, buffaloes play an important role on the farms, especially in rural areas. It is said that “The husband ploughs, the wife sows, water buffalo draws the rake and are friends of the children." People can easily see the images of buffaloes plowing rice fields or transporting people from sunrise to sunset. However, the best relax-able and enjoyable time of them is the hottest part of each day when submerging in water to remove skin parasites and other pests.
