Character by character
Origin and story
Historical accountWen Tianxiang's preface to his Ji Shi poems recounts an argument in the Mongol camp with Lü Wenhuan and Lü Shimeng, whom he bitterly condemns for surrendering. Even though he is in their power, Wen refuses to soften his accusations. His account says that when the exchange was reported to Bayan, the commander called him 心直口快, recognizing his unguarded directness.
The phrase is therefore attested in a Song writer's account, as well as in later Yuan drama. It describes someone who says what they think readily and without concealment. That candor can be admired, though it may also be tactless.
