His name is Chen Danian, he is 35 years old, has no education and no background.
Dragging a family of five from the countryside into the city, they make a living by running takeaways on a second-hand battery car.
During the day, he rushed between high-rise buildings and suffered cold looks, difficulties and hardships in life;
At night, he stared at his meager income and calculated the rent, tuition fees and medicine expenses for the elderly.
There are old people at the top and young people at the bottom. There is no retreat behind them and they dare not stop.
This is a true record of a middle-aged father struggling to make a living in the cracks of the city.
