Du Mantang, the alleyway steward of "Kuaguzhou Hutong", is a well behaved person in the alley, while Zhang Zezhong, who faces him, is slick and likes to take advantage of small things. Although they have grown up, they have never been able to deal with each other due to their completely opposite personalities. A reality show shoot sparked a long-standing grudge between the two, and during a subsequent inspection team, the conflict escalated in the basement incident. In their repeated battles of wits and courage, the two caused a series of comical accidents.
