Legend has it that Liu Yong, a native of Dongguan in ancient times, had a peculiar fondness for eating scabs from people's sores. He found that they tasted like abalone.
Once, he went to visit Meng Lingxiu. Meng Lingxiu had recently suffered from a burn sore, and scabs had fallen onto his bed. Liu Yong picked them up and ate them with great relish, startling Meng Lingxiu, who immediately urged him to stop.
