AI detection tools mistakenly flag classic Chinese literature like Zhu Ziqing's Moonlight on the Lotus Pond as AI-generated with high probability due to their extensive use in training AI models. Experts clarify that the percentage reflects the likelihood the entire text is AI-generated, not the portion written by AI, and warn these tools are unreliable for judging originality, as results vary widely by platform and text length. They advise maintaining a unique writing style to counter such algorithmic errors.
