打隔山炮

打隔山炮

Literally means:

beat about the bush; talk bunkum; talk behind one's back

Actually means:

If a cannon is fired toward something that is blocked by a mountain, it's very difficult to aim directly and hence hard to hit the target. The phrase figuratively means saying words that are deviated from the theme, which is of no use to solve the problem.

It figuratively means talking behind one's back instead of telling others frankly his opinion, suggestion or criticism.

隔着山打炮，不能直接瞄准,很难打中目标。比喻说的话离开主题，对事情没有任何帮助，对解决问题没有任何作用。

比喻不当面说出自己的想法，或提出批评或意见,而在背后议论。
