I am Zhou Shaoheng. I have concealed my past identity as a marquis and settled in the deep alleys of the old city. I record all kinds of folk customs and strange things around me from a first-person perspective. From the old customs of keeping old years old in old lanes and old houses to the legends and legends in suburban villages, I relied on my accumulated experience in the past to dismantle the mysteries of various customs, and in the smoky urban daily life, I uncovered the warm past hidden behind each folk custom.
