1. Is this request related to a challenge you're experiencing? Tell me about your story.

Sometimes the results provided by large models are not ideal, containing errors or being too short. I need an "if" judgment node to determine if the content is appropriate. If it's not suitable, I want to regenerate the content and retry up to three times. How can I implement this scenario?
