In Chinese, Pinyin is m í NGB á Ili à OD à ng, which means to speak or do things cleanly. It's from flowers in the mirror.
The idiom comes from chapter 79 of Jing Hua Yuan written by Li Ruzhen in Qing Dynasty: "I see that the difference method in the calculation book has the names of decreasing, double decreasing, 37, 46, etc., which are different. How can we get this clear and clear."
