Chang Mei-Lan is searching for her real parents.
She thinks that the ones that she has now can’t possibly be her real parents.
They are illiterate and can’t understand most things without her help.
For this elementary student, her parents’ weakness is something that she can’t easily understand. It’s an embarrassing fact she would rather keep a secret, especially from her peers.
But the more she searched, she realised that what she has been looking for has been right in front of her this whole time.
