Glance at your phone, learn something new, and come back tomorrow for the next one. Chengyu (成语) are the short, vivid sayings Chinese speakers use every day. Each one carries a story, often centuries old, and knowing them makes your Chinese sound natural. ON YOUR HOME SCREEN The widget shows today's page, just like a real tear-off calendar: • The date, with the day of the week • The idiom, broken down character by character, with pinyin and an English meaning for each • What the whole idiom means • An example sentence, with pinyin and an English translation A new page arrives every morning. 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! Switch between Simplified and Traditional characters at any time, and every page changes instantly.
