The worship of T’ai Sui seems to have first taken place in the reign of Shên Tsung (A. D. 1068–86) of the Sung dynasty, and was continued during the remainder of the Monarchical Period. The object of the worship is to avert calamities, T’ai Sui being a dangerous spirit who can do injury to palaces and cottages, to people in their houses as well as to travellers on the roads. But he has this peculiarity, that he injures persons and things not in the district in which he himself is, but in those districts which adjoin it.

Thus, if some constructive work is Page 197undertaken in a region where T’ai Sui happens to be, the inhabitants of the neighbouring districts take precautions against his evil influence. This they generally do by hanging out the appropriate talisman. In order to ascertain in what region T’ai Sui is at any particular time, an elaborate diagram is consulted. This consists of a representation of the twelve terrestrial branches or stems, ti chih> and the ten celestial trunks, t’ien kan, indicating the cardinal points and the intermediate points, north-east, north-west, south-east, and south-west. The four cardinal points are further verified with the aid of the Five Elements, the Five Colours, and the Eight Trigrams.

By using this device, it is possible to find the geographical position of T’ai Sui during the current year, the position of threatened districts, and the methods to be employed to provide against danger.
