**Key considerations when choosing:**

* **Target Audience:** Who are you writing for? Are they beginners, or more experienced in the topic?
* **Content:** What kind of content do you actually publish under this tag? The description should reflect that.
* **SEO:** Think about relevant keywords. While these descriptions aren’t for SEO in the traditional sense, using terms like “星座” (astrology), “生肖” (Chinese zodiac), “占卜” (divination), or “命理” (metaphysics/destiny) helps people understand the content.
* **Conciseness:** WordPress tag descriptions should be reasonably short.
