We can thank Shakespeare for committing the phrase "Carry your heart on your sleeve" — or being transparent — to paper. Iago famously says it in "Othello."
我们应该感谢莎士比亚，因为是他将“把心戴在袖子上”（carry your heart on your sleeve）写在纸上，意思是轻易表露感情，是《奥赛罗》中伊阿古的名言。
In OthelloAct 1 Scene 1, Iago says “But I will wear my heart upon my sleeve…” meaning he would be exposed.
《奥赛罗》第一幕第一场，伊阿古说：“但是我会把心戴在袖子上”，意味着他会敞开心扉。
Aside from Shakespeare's genius brain, other possible origins include the tokens knights would wear from ladies during jousting matches and a marriage festival from the Middle Ages.
除了天才的莎士比亚，这句话还有可能来源于中世纪马上长矛比武中贵妇赠与骑士令牌，或婚礼场合，等等。
