The dad is the world's top killer. He is tired of fighting in the world, so he lives in seclusion in Qinglong Town with his son. He opens a barber shop in Qinglong Town. He wants to live a stable life, but his enemies will not let him go; the police are investigating him; a fierce woman wants to knock him down, and he is very troubled.
His son Doudou is always naughty and makes trouble, which really gives him a headache. Doudou: Dad, what kind of head shape is that? Dad: Son, that's called Shamate. Doudou: Their heads are really flat! So all the Shamats became bald...
