Wei Zi's quotation of animal stories.

Does the subject want to ask "Wei Zi alludes to the story of what animal buddhist nun is"? The story of Paiyuncuo is about an old man who caught a white crane and put it in a cage. Later, the crane was released and returned to the free sky. However, the crane insisted on returning to the old man's home and spent the rest of his life quietly. This story expresses the preciousness of freedom and family, as well as the qualities of loyalty and gratitude.
