Advance and retreat
Chinese idiom, Pinyin is j ì NF ǔ Tu ì f ǔ, which means that advance and retreat are not uniform. From the book of rites, music.
The idiom comes from "the book of rites · the record of music": "today's husband's new music, advance and retreat, adultery to excessive, drown and more." Zheng Xuan's note: "Fu you Qu also, words are not the same." Kong yingdashu: "it's called bent and tortuous. You can't advance and retreat in unison. It's all flexion, advance and retreat, and the army is messy."
