**Choosing the right option depends on:**

* **Your audience:** Are they technical or non-technical?
* **The purpose of the tag:** Is it for general troubleshooting, specific topics, or a broader discussion?
* **The overall tone of your website:** Are you formal or informal?

You can also adjust the description further to be more specific to the *type* of product or service you’re discussing. For instance, if dealing with software, you might mention “軟體操作疑問” (ruǎntǐ cāozuò yíwèn – software operation questions).

Remember to consider the overall keywords you want to associate with this tag and how it will help users find relevant content. Good luck!
