Translation and context#
The full-expression translation above is an editorial teaching translation. The dictionary source verifies the component vocabulary; it is not evidence that a particular speaker said this sentence. Context supplies the speaker, listener, time and intended tone. The pinyin is a reading guide rather than a phonetic transcript of natural conversation.
