Chinese phrase translation: 敲边鼓 (qiāo biāngǔ) Beat the drum on the side

敲边鼓 (qiāo biāngǔ) Beat the drum on the side; to speak in support of somebody; speak a good word indirectly for sb.

Usage:

边鼓是一种小型的鼓。戏曲表演中，主角出场前，或剧情进入紧张时刻，鼓手就以很快的动作敲响边鼓。边鼓是为突出主角和渲染气氛服务的，所以“敲边鼓”也用来比喻从一边帮腔、助势，帮说话人表达某些思想观点好让其他人认同。 (有些许贬义)。
“边鼓”is a small dram. In drama performances, the drummer plays it quickly before the leading actors appear or when the plot enters into the tight time. “边鼓”serves for highlighting the protagonist and rendering atmosphere. So “敲边鼓”also refers to somebody speaking aside in support of others, in order to make others agree with the speaker. (This word sometimes has a derogatory sense.)
