* **Keywords:** The keywords in Option 4 (like 賀卡, 感恩卡) are very useful for search engine optimization (SEO). The more specific, the better.
* **Brevity:** WordPress tag descriptions are often best kept concise.
* **Action-Oriented:** Consider including a call to action (e.g., “Learn how to…” or “Explore the latest trends…”) if appropriate. Though, in this case, just outlining what’s covered works well.

I recommend **Option 2** or **Option 3**. They provide a good balance of clarity and informativeness, making it clear to the reader what kind of content is tagged with “卡片.” If you want to improve SEO, consider incorporating some related keywords from Option 4 into your chosen description. Good Luck!
