Each one carries a story, often centuries old, and knowing them makes your Chinese sound natural.

IN THE APP Tap the widget to open the full page and go deeper: • Its history: where the idiom came from, and how it came to mean what it does now • More examples: three more sentences showing how it's used, each with pinyin and an English translation TRADITIONAL OR SIMPLIFIED, 都可以!
