One of the most exciting aspects of the festival are the various, (and sometimes gruesome) ceremonies which are held to invoke the gods. Firewalking, body piercing and other acts of self mortification undertaken by participants acting as mediums of the gods, have become more spectacular and daring as each year goes by. Men and women puncture their cheeks with various items including knives, skewers and other household items. It is believed that the Chinese gods will protect such persons from harm, and little blood or scarring results from such mutilation acts. This is definitely not recommended for the faint hearted to witness.
