In Thailand, The Nine Emperor Gods Festival is called thetsakan kin che, the Vegetarian Festival. It is celebrated throughout the entire country, but the festivities are at their height in Phuket, where about 35% of the population is Thai Chinese. It attracts crowds of spectators because of many of the unusual religious rituals that are performed.
In accordance with the traditions, many religious devotees will perform ritualized mutilation upon themselves and one another while under a trance-like state, including but not limited to: impaling through cheeks, arms, face, legs, back etc., with everything from as small as syringes to as large as is agreed upon between all members; partial skinning (the skin is not removed, just cut and flipped over); slashing of limbs, chest, stomach and especially tongue with swords, axes and knives; bloodletting; removal of tissue (normally limited to cysts) and intentionally wrapping or standing near fire crackers as they are lit.
This is done without anesthetic, always inside or near the temples surrounded by other devotees with only iodine, petroleum jelly and surgical gloves as precautionary measures. Despite this scenario, many of the people performing the rituals are also the people who will care for many of the people in their recovery.
