In the Chinese world, ships came to be used as a ritual object. Three examples of this are chosen. The geographic distance between them is relatively great, and there is no obvious direct influence or transmission link between them, yet they all possess the features of the“inspection by decree.”The “inspection by decree”is identified as the standard form of ship ritual in the Jiangxi江西, Fujian福建, Taiwan and the south-east Asia areas, the argument being that it once formed part of a national ritual code.We can examine such use in Fuzhou 福州and the two cities of Zhangzhou 漳州and Quanzhou 泉州. In order to rationalize the customary belief in“seeing off the Five Emperors and the God of Plague,”Confucian scholars who thoroughly understood the imperial inspection rites made changes to them, incorporating the rituals for seeing off pestilence and plague, and then restricted their use in order to control the main rites for greeting and sending off the Emperor. The“inspection by decree”came to be a glorified name, and so in order to legitimize the Five Emperors rite, it could thus be standardized as a structure for greeting and sendoff rituals. Understanding the reasons for the intervention of Confucian officials also brings us to understand that the aim and motivation for the simulation and appropriation of the imperial inspection rites was to deliberately avoid prohibition by the authorities. However, even after integrating these folk and Taoist myths and rituals, there was no way to completely change the nature of the gods and spirits as those who brought on or saw off pestilence and plague, and the feelings of fear and respect for the Plague God were merely transferred onto the Emperor and to his inspectors arriving to inspect the border. Thus the King’s ship was used as a ritual symbol for seeing off the King back across the border, and is one that can be used to examine the other two forms: the ship paintings used in Lantern Festival exorcisms and the Nine Emperors’ Ship used during the Nine Emperors’ Festival. I believe the reason these can be regarded as divergent types is that within the standardized ritual structure, they were more related to exorcistic rites, such as seeing off plague or driving out evil. One of the main send-off rituals is performed in the Ji’an area of Jiangxi, in which a ship is painted on paper, cloth or wood. Another, the Nine Emperor’s Ship, is popular in the south-east Asia area. The standardization of the myths of the gods and spirits and of the structure of rituals that appeared within each region shows that although these places were far from the control of central political power, not only did the local populace seek standardization, they also possessed the ability to create new myths and rituals. As the chief impetus came from the fear of epidemics and plagues, annual or periodical cleansing was performed through ritual symbols, resulting in the formation of a society of two worlds, the “ordinary and extraordinary.”Ships at waterfronts and docks everywhere were a common means of crossing over the border. In transforming them into a ritual means for sending off the inspection by decree, a real crossing of borders was transformed into a crossing of boundaries in a religious sense, and they came to be used as a culturally symbolic object within the context of the ritual, linking this world with the other world. Thus they became a manifestation of material culture; although it is a belief known only locally in Jiangxi, Fujian or Taiwan and south-east Asia, as far as the idea of periodical cleansing is concerned,“inspection by decree”encapsulates a certain universal experience and wisdom.
