He saw that the clothes of the villagers on both sides of the Baihe River in Nanyang were not properly covered, and many people's ears were frozen. He was very sad, so he asked his disciples to set up a medicine shed in Guandong, Nanyang, and put mutton, peppers and some cold-dispelling herbs in a pot to cook, take them out and chop them up, and then cook them in a pot. A medicine called "Quhan Joule Decoction" was given to people. After taking it, the villagers' ears were cured. Later, people imitated it every winter solstice, which led to the custom of "pinching their ears" From the late Qing Dynasty to the early Republic of China, people in Hangzhou liked to eat rice cakes on the solstice in winter.
