Four hundred years ago, in the ancient city of Jiading, the snow had not melted and the wind was biting.But at the end of this deep winter, spring brings a warm breath.Firecrackers sounded in every corner of the village, children were playing in front of their homes, and adults were busy replacing old talismans with new ones to welcome the new year.It was the first day of the Lunar New Year after the 30th. Early in the morning, Tang Shisheng, a famous scholar in Jiading, was sitting at home, while students from far and near rushed to Tang's house one after another to pay New Year's greetings to their teacher.The old man didn't care about the richness or poverty of his visitors, so he only used the vegetables he grew at home to make New Year soup, allowing them to taste the simplest taste.
