In folklore there are many things, symbolic phenomena, and the pig is an image of multiplication, proliferation, prosperity, development. That's why the old grandparents said, "Rich to raise dogs, difficult to raise pigs", or: "Women have to raise pigs / Times are poor to raise buffaloes." The image of a woman with a negative tone like Earth, representing the multiplication and raising of all things, must know how to raise pigs to increase for the family, helping the virtue to take care of the prosperous and warm family. So folk paintings with pigs or being bought to hang in homes on New Year to pray for good luck, fortune, prosperity will come to the homeowners in the new year. Dong Ho painting not only shows the image of prosperity through a large herd of pigs, but also explains the reason for this reproduction and growth. Through that message reminds people to know according to that rule to achieve a peaceful, happy life.
