Like Father and Son (2020)

Original title: 拨浪鼓咚咚响

Guoren travels the villages, selling goods of all kinds while he hunts for the man who stole the money for his son's care. Madou, one of the many abandoned children in the villages, hides in Guoren's truck so he can look for his father. A powerful but cathartic trip through rural China with a neorealist touch and non-professional actors who add authenticity to the story, prompting spontaneous laughter despite the challenging issues involved.
