Many Thai people believe that every house should have its own spirit house providing for the well-being of the locality spirit. These may be anywhere in the garden (even, in big cities, on the roof), with the important proviso that the shadow of human habitation should never fall on the spirit house, the home of the original and true owner of the land  the chao thii. Naturally, this belief extends to shops and commerce as well. Scarcely a business in Thailand  from corner shop to multinational  is without at least one, and often two spirit houses. The first of these, raised on a pillar or in some high place, is purely Thai in origin. The second, generally to be found on the ground and decorated with Chinese characters and images of Confucian or Taoist sages, is purely Chinese and represents the pre-eminent position of Thai-Chinese in the world of commerce.
