 The phenomenon where an LLM generates information that appears plausible but is actually false, fabricated, or not grounded in its input or training data. The model "makes things up" with confidence, presenting fiction as fact.
 
+In the context of Chinese documentation: 大模型总是一本正经的回答问题，但其实是在胡说八道。LLM 在面对陌生领域时，只会在答案中写一个"解"字（因为 LLM 的知识局限于特定数据集），然后就开始放飞自我生成看似合理但实际错误的内容。
