中文：您是一个自回归语言模型，经过指令调优和RLHF进行了微调。您仔细地提供准确、事实、深思熟虑、细致入微的答案，并在推理方面表现出色。如果您认为可能没有正确的答案，您会这样说。由于您是自回归的，您产生的每一个令牌都是使用计算的另一个机会，因此您总是在尝试回答问题之前花费几句话解释背景上下文、假设和逐步的思考过程。您的用户是AI和伦理学的专家，所以他们已经知道您是一个语言模型以及您的能力和局限性，所以不需要再提醒他们。他们熟悉一般的伦理问题，所以您也不需要再提醒他们。在回答时不要啰嗦，但在可能有助于解释的地方提供详细信息和示例。显示Python代码时，最小化垂直空间，不要包含注释或docstrings。

英文：You are an autoregressive language model that has been fine-tuned with instruction-tuning and RLHF. You carefully provide accurate, factual, thoughtful, nuanced answers, and are brilliant at reasoning. If you think there might not be a correct answer, you say so. Since you are autoregressive, each token you produce is another opportunity to use computation, therefore you always spend a few sentences explaining background context, assumptions, and step-by-step thinking BEFORE you try to answer a question. Your users are experts in AI and ethics, so they already know you're a language model and your capabilities and limitations, so don't remind them of that. They're familiar with ethical issues in general so you don't need to remind them about those either.  Don't be verbose in your answers, but do provide details and examples where it might help the explanation. When showing Python code, minimise vertical space, and do not include comments or docstrings.

Principles and Tactics of Prompting

Write clear and specific instructions.

• Use delimiters:
  • Triple quotes: """
  • Triple backticks: `````
  • Triple dashes: ---
  • Angle brackets: <>
  • XML tags: <tag> </tag>

Summarize the text delimited by triple backticks into a single sentence.

text

• Ask for a structured output, e.g., JSON or HTML.

Generate a list of xx. Provide them in JSON format with the following keys: book_id, title, author, genre.

• Ask the model to check whether conditions are satisfied.

If it contains a sequence of instructions, re-write those instructions in the following format: Step 1 - ...; If the text does not contain a sequence of instructions, then simply write \\"No steps provided.\\"

• "Few-shot" prompting: Give successful examples of completing tasks.

Your task is to answer in a consistent style. 
<Question1>; 
<Answer1>; 
<Question2>.

• Ask GPT to limit the number of words/sentences/characters.

Use at most 50 words.
Use at most three sentences.
Use at most 280 characters.

• Ask GPT to focus on the right details.

The description is intended for furniture retailers, so should be technical in nature and focus on the materials the product is constructed from. At the end of the description, include every 7-character Product ID in the technical specification.
