孩纸别放弃治疗啊
[hái zhĭ bié fàng qì zhì liáo a]
The term 'child (paper) do not give up on your treatment' sounds funny due to the wordplay. “Paper” is used to refer to children because 'child' in Mandarin has similar pronunciation as paper ('Kid'='孩纸' and 'Children'= '孩子'), so people will find it comical while delivering a warm - hearted advice to not give up hope for medical recovery.
