Former boxing champion Chu Tian retired due to injury and returned to the old city to open a community fighting gym. I wanted to live a quiet life, but found that my neighbors all had their own difficulties: bullied vendors, rebellious left-behind teenagers, lonely empty-nesters, and unemployed middle-aged uncles. Chutian used his fists to drive away oppression and healed people's hearts with warmth. In the process of teaching ordinary people to box, he rediscovered the meaning of life and revitalized the entire old street. An urban story about strength and tenderness, blood and healing begins here.
