How does a “mental patient” live in a normal world?

Wang Zhantuan (Ge You) is a strange man in the world, occasionally crazy and eccentric, but uniquely sane. Zhou Zheng (Wang Junkai) is a sensitive and silent teenager who is self-absorbed due to his stutter, but has a silent backbone. The two misfits make a big family headache and farce...

This movie is adapted from the short story “Immortal Disease” written by Zheng Zhi.
