中国有句古话叫“明枪易躲暗箭难防”，你知道这句话用英文怎么说吗？
放冷箭，中文俗语，“冷箭”同“暗箭”，表示“an arrow shot from hiding”，放冷箭指“乘人不备，放箭伤人（to shoot at someone from a position where you cannot be seen）”，比喻“暗中伤人”，英文可以翻译为“stab in the back”，或“resort to underhand means”。
- 明枪易躲，暗箭难防。
It is easy to dodge a spear in the open, but hard to guard against an arrow shot from hiding. - 哈曼声称，嫉妒的同事暗箭伤人，她是受害者。
Harman claimed she was the victim of backstabbing by jealous colleagues. - 他们说了会支持我，但是事实上，他们却在背后放冷箭！
They told me they would back me up. But as a matter of fact, they stabbed me in the back.
