Pig head rice was originally a dish eaten by poor families during festive occasions, but it was popularized by the people of Yanshui and has become a local specialty. To make pig head rice, a whole pig head is cooked with the rice, infusing the rice with the distinctive aroma of pork fat. The pig head can also be sliced and served as a side dish. The unique flavor of pig head rice can only be found in Yanshui.
