Plot

Xiao Pang is a mischievous young boy. To the chagrin of his parents, he has no interest in studying and is always eating. His mother arranges extra tuition classes for him to try to whip him into shape, but the stress leaves him despondent and depressed instead. At the end of their wits, his parents promise him a mobile phone if he does well in his exams. He works hard and earns the phone, but a new problem then crops up: phone addiction. Xiao Pang`s parents call renowned child psychologist Dr Ke for help, but as they are about to leave for their appointment, they realise that Xiao Pang has gone missing.
