Blaze Away

You cannot exactly say TVB is wrong, it is just not a common way to say 加把勁. Honestly it is the first time i heard it too. But definitely not wrong... really a matter of interpretation...

Here is an example... " Break a leg "

Direct Translation = break a leg... actually damage leg , leg injury
Actual Meaning = keep up the good work! as Chinese say.... " add oil "

Hope you understand what i mean.

Good Luck!!

不同字典都有不一樣的意思﹐這詞語大概是指熱情﹑激烈﹑努力的意思。所以不能說TVB是錯的﹐只要是類似這個意思﹐那都算對。
