In 1979, veteran Chen Shanhe gave up his resettlement and voluntarily returned to the family home of his hometown "Guangming Textile Factory" and became a clerk in the street office. Faced with a series of "explosions" in employment, housing, and public security caused by the wave of people returning to the city, he used the organizational skills and public spirit he had developed in the army to lead this "city where three religions and nine streams gathered, and which was on the verge of losing control, starting from renovating a public toilet and setting up a lunch box stall for educated youths." "Corner" has been gradually transformed into a nationally famous "harmonious demonstration community" during the changes of the times for twenty years. The fates of him, Shen Jing, a female textile worker, Xiao Chunsheng, an educated youth who returned to the city, and others are also intertwined here, creating an "epic of grassroots governance" that belongs to ordinary people.
