I have discovered the most perfect creature in the entire universe!

From childhood to adulthood, it has never done a bad thing, has no flaws, parents all want to raise it, teachers never criticize it, it can get near-perfect scores in every exam, and when it grows up it will always get into a prestigious university, pass the postdoctoral exam, always find a good job and achieve great事业, has no criminal record, doesn't smoke, drink, or visit prostitutes… and also has an excellent, very wealthy spouse. This kind of being is called 'other people's child'!
