The original sentence of "Dancing in Shackles" is: Literary creation should be like dancing in shackles. The shackles are rhythm. We must follow the rhythm, but not be restricted by it. We must dance with our own dance steps while wearing shackles. . From Wen Yiduo.

Goethe also put forward a similar point of view: "Responsible freedom, dancing in shackles". His original intention was that when poets create poetry, it is like dancing in shackles. What he calls shackles is meter. .

Different understandings:

Over the years, the understanding of this shackles by poets has divided into two extremes, one is "shackles are necessary" and the other is " There can be no shackles."

Anything that goes to extremes is wrong, and poetry is no exception. Freedom has always been limited by objective existence in behavior. While observing objective laws, we should find the extension of the laws and even break through this, which is the broad sense of freedom. Respect, inheritance, promotion and expansion are also the laws of poetry development.
