Specifically, a trapped dragon is like a trapped dragon, unable to fly freely in the sky, but trapped in a narrow space, unable to show its strength and ability. This metaphor is sometimes used to describe a person in a difficult situation, unable to break through his own limitations and exert his potential.
In the Book of Changes, the image of the trapped dragon usually appears in the fourth chapter, that is, the chapter of "the trapped dragon wandering". This image symbolizes that a person is in a predicament, but through his own efforts and wisdom, he can break through the predicament and move towards success.
