Here are a few options for the description of the “證券” tag, tailored for a WordPress context, ranging from simple to slightly more descriptive:

**Option 1 (Simple & Concise):**

> 關於證券的文章。 (Articles about Securities.)

**Option 2 (Slightly more Descriptive):**

**Option 3 (Focus on Education):**

**Option 4 (Focus on Market Updates):**

**Option 5 (More Comprehensive, could be used directly on a tag archive page):**

**How to decide which option to use:**

* **Character Limit:** WordPress might have a limit on description length, so choose accordingly.
* **Purpose of the Tag:** What kind of content is primarily associated with this tag? Is it primarily for news, education, or market analysis?
* **Target Audience:** Who are you writing for? Novices or experienced investors?

I recommend **Option 2 or Option 5** (depending on length), to create good context for your audience. Remember to also use clear keywords in your post titles and content to help with both search engine optimization (SEO) and user understanding.
