What does it mean to dance in shackles or on the point of a knife?

Expressing the dancer's yearning for freedom and unlimited fighting power.

Dancing with shackles, most of them are some of the dances with the theme of breaking free, the dancers try their best to show a kind of breaking free from shackles, the pursuit of freedom of the meaning of the dance, used to warn people not to be too confined, to express themselves. The moral is to have some shackles. It is generally used as a metaphor for having good actions or ideas that are constrained by some external factors that prevent them from developing fully and freely.

The dancer on the tip of the knife, the tip of the knife, is a condition that people can not tolerate. Dance is an art. Dancer, is to treat life an attitude. Dancer on the tip of the knife, is in great pain but instead demonstrated the life of human nature in the most beautiful "skill" and quality. This word is a far greater compliment to man than an ordinary praise. It goes back at least as far as the Daughter of the Sea. Of course it is not only used to summarize a certain kind of life, but also in a narrower sense.

Expanded:

Dancing in shackles is a famous quote by the American critic Perry. He intended to say that poets are actually dancing in shackles when they create poetry, and by shackles he meant the meter of the poem. But the quote is actually just as much a philosophy of life.

Life always has a lot of heavy burdens, if you can under the heavy burdens, still maintain a good state of mind, still be able to make their lives beautifully dance, then this is destined to be the most wonderful dance. It is the dance that best reflects your wisdom and talent.
