The ritual held by the village for the inauguration of the tiger's grave house involves a goat, a pig and a chicken as offerings, which are put on a tray and then in the grave house. The village head's prayer would be as follows: As giang vo wishes to stay in the village, it must protect the villagers from death; when there is war between this village and other villages, giang vo must keep the village informed through dreams, as early as possible; if any one attempts to destroy or burn the village, giang vo must punish him/her. Local women and visitors from outside are not allowed to attend the ritual dedicated to the head of the tiger. If a visitor from another village wishes to attend the ritual, the village head must be informed and would take a decision. The tiger's grave house is usually located on a higher ground in the vicinity of the human graves house, and no one is allowed to enter it. It is surrounded by a stone hedge. In the middle of the house is a stone on which is placed the tiger's head. The house also contains a number of presents given by the villagers to the tiger: a bowl (for containing food), armlet, a “reng” piece of cloth, buffalo and cow horns, pig's jaw which have been prepared and contributed on the instruction of the village head. When the Rong house is inaugurated, when new year celebrations and new paddy celebrations are held each year, some food, including new rice, must be presented to the tiger spirit. The tiger's grave is visited and cleaned once every year by the villagers. Tigers are worshipped because people believe that the worshipped tiger would keep them informed through dreams about such bad happenings as war, crop failure or epidemics. In Laos, some villages worshipped two tigers’ heads. At present, only Nham I hamlet continues to worship tigers as a custom. Ka Linh, Ta Keu hamlets worshipped tigers when they were still located in Laos. One can say that from the end of the anti-US war, such a worship no longer prevails in the Ta-oi ethnic community. Love magic This ethnological term refers to the practice of some minority ethnic groups who are adept in using some products for inducing a girl and turning her into one's wife. The Ta-oi call that product as “love medicine”
