PLOT
In northern Shaanxi, those three-wheeled trucks who came to the city from rural areas came to be suffering. They talked hard and finally sent their children to distant universities. Four years have passed, the big children can't find a job, the future is uncertain, the smaller children have come to the age of the university. It seems to be in the instinct, a family is still like a hen hatch, waiting for the new hope to break out.
