Retired soldier Yang Qing faces a parenting dilemma - his fourth-grade son Yang Xiaoyang is addicted to games and is at the bottom of his class. After trying all educational methods failed, this grassroots community worker made a surprising decision: he took his son on an electric bike every night and shuttled through the streets and alleys of the city to deliver food. They not only delivered food, but also delivered a journey to repair the relationship between father and son. Behind each order, they also encountered the warmth and edges of the city.
