Bié zài shuō nàxiē guānmiǎn-tánghuáng de lǐyóu le.
Stop giving those high-sounding excuses.
Tips
usage
Often appears in the four-character phrase 冠冕堂皇 (guānmiǎn-tánghuáng) meaning 'pompous and high-sounding' — usually with a sarcastic edge implying the words are empty.
memory
冠 (guān) = cap and 冕 (miǎn) = ceremonial crown; together they paint the picture of a fully crowned ruler — hence 'dignified' or, when applied to talk, 'pompously formal.'
