**Key Considerations When Choosing:**

* **Website’s Tone:** Adapt the description to match the overall tone of your website or blog.
* **Target Audience:** Consider who your target audience is. Are they completely new, or do they have a little basic knowledge?
* **Content of the Posts:** Make sure the description aligns with the type of content you’ll be tagging with this term.
* **SEO:** While post tag descriptions don’t have a huge impact on SEO, you could include relevant keywords like “股票 (stocks)”, “基金 (funds)”, “ETF” if your content covers those topics.

You can also tailor your choice based on your personality and what you want your readers to feel when they see the tag. I personally like Option 4 for a WordPress Post Tag becasue it gives more information. Choose the option that you think best fits your needs!
