The brief reunion and professional characteristics are concentrated in this short three minutes. The three-minute countdown at the top of the screen collides with the multiplication formula recited by the children, which stimulates the audience's cognition and understanding of the protagonist's career and family conflict. Departure and arrival, parting and lingering are all concentrated in this short three minutes; Liveliness and silence, self and great love are all branded in this short three minutes. The passengers' longing and longing for going home, and the persistence and dedication of the service providers in the Spring Festival travel rush craze, reflect a different picture of floating China in the connection between the train and the platform. The three-minute meeting on the podium expressed Chinese people's feelings for their homeland with prose-like brushstrokes.
