In this video One Child Policy: Last Week Tonight with John Oliver (HBO) there's a description of only children:
little emperors or little meatballs as they're sometimes called in Chinese
These terms are referring to spoiled only kids.
Little emperor is easy: 小皇帝. But I don't think I've ever heard mention of "little meatballs." What's the original term? 小丸子? 小肉丸?
Any ideas? Where'd the term originate from?
