# Ong Yah

Ong Yah (Chinese: 王爺; Pe̍h-ōe-jī: Ông-iâ; lit. 'Royal Lord') are deities in Hokkien folk religion in Fujian and Taiwan, frequently considered an aspect of the Taoist belief system. Ong Yah is particularly worshipped in Southern Taiwan and also among Hoklo communities worldwide.
The customary belief is that Ong Yah are Divine Emissaries who tour the world of the living on behalf of the Celestial Imperial Order, expelling disease and evil from those who worship and seek their divine grace. A temple dedicated to Ong Yah is usually called Tāi-thian-hú (代天府, "Palace representing (the son of) Heaven"), and the Ong Yah's visit is known as Tāi-thian-sûn-siú (代天巡狩, "Celestial Imperial Inspector representing the (son of) Heaven"), the object of the "inspection" being disease and bad luck. Such "inspection tours" take place on a regular cycle of a set number of years, usually three years but may varies at different region.

## Origins of Ong Yah worship

Ong Yah worship stems from belief in two main categories of supernatural beings, both of which are spirits of what were once, according to legend, real human beings with selfless attitude and noble character.
The first category of Ong Yah belief began with the legend of a kind-hearted intellectual who sacrificed himself by committing suicide in a well that contained toxic water, in order to prevent the villagers from drinking the well water and thus avoided any pestilence or plague from spreading. Therefore, to stop diseases, like pestilence, from spreading, people would honoured and make offerings to those beings who sacrificed their own lives for the civilians and public well-being. As time passed by, these great people are honored as Ong Yah and gradually became local Guardian Deities that are able to dispelling epidemic and diseases, and bestow blessings and good fortune.
The second category comprises national heroes who are bestowed with the status of Deity by the Celestial appointment of Jade Emperor due to their heroic deeds and great sacrifices in their lives. An example is the spirit of Koxinga, thus honored for his role in defending and protecting Han Chinese against the Qing invading forces in China and the Dutch colonial forces in Taiwan.
