**How to choose the best description:**

* **Consider the content:** What type of posts will be tagged with “年代資訊”? Are they mostly historical events, or do they include things like fashion, technology, or music?
* **Consider the audience:** What kind of people are you trying to reach? Choose a description that is clear, engaging, and easily understood.
* **Keep it concise:** WordPress tag descriptions are usually shown as a snippet, so keep it relatively short and to the point.

I recommend choosing Option 2 or Option 4 if you’re aiming for broad coverage, or Option 1 if your site’s core focus is very historical. Choose the one that best reflects the overall content of your blog! Remember to use a well-organized category taxonomy to ensure clarity for your visitors.
