talking mends no holes.
空谈无补。
talk of the devil and he will appear.
说曹*，曹*就到。
tall trees catch much wind.
树大招风。
teach others by your example.
躬亲示范。
the best hearts are always the bravest.
无私者无畏。
the best man stumbles.
伟人也有犯错时。
the cat shuts its eyes when stealing.
掩耳盗铃。
the danger past and god forgotten.
过河拆桥。
the darkest hour is nearest the dawn.
黎明前的黑暗。
the darkest place is under the candlestick.
烛台底下最暗。
