It tells the sad life of a delivery boy. The suffering in the world reappears, and the platform crushes all living beings into misery. I first entered the society, running around the streets, alleys, buildings and communities of the city, and I also saw the warmth and ups and downs of human relationships, the joys and sorrows of separation and separation. This work is only for delivery workers to have their own work, and for the delivery workers group to have a voice.
