LangChain默认的Prompt

template="Use the following pieces of context to answer the users question. \nIf you don't know the answer, just say that you don't know, don't try to make up an answer.\n----------------\n{context}"

我自己Prompt替换了之后

template="Use the following pieces of context to answer the users question in Chinese.\n If you don't know the answer, just say that you don't know, don't try to make up an answer.\n There are multiple answers, provide each answer in Chinese,specify the source file for each answer.\n \n\n{context}
