Two wrongs do not make a right. 別人錯了，不等於你對了。

Two of a trade seldom agree. 同行是冤家。

Two heads are better than one. 一個好漢三個幫。

Two dogs strive for a bone, and a third runs away with it. 鷸蚌相爭，漁翁得利。

Turn over a new leaf. 洗心革面，改過自新。

Truth never grows old. 真理永存。

Troubles never come singly. 福無雙至，禍不單行。

Touch pitch, and you will be defiled. 常在河邊走，哪有不濕鞋。

To save time is to lengthen life. 節約時間就是延長生命。

Too much praise is a burden. 過多誇獎，反成負擔。
