Here are a few options for a description for a WordPress post tag with the title “基數” (jīshù, meaning “cardinal number” in Traditional Chinese), varying in length and focus:

**Option 1: Concise and Direct**

* **Description:** 關於基數的標籤。 (Guānyú jīshù de biāoqiān. – A tag about cardinal numbers.)

**Option 2: More Descriptive**

* **Description:** 此標籤聚集了有關基數 (例如一、二、三等) 的文章。 涵盖各种数字表达方式和概念。 (Cǐ biāoqiān jùjí le yǒuguān jīshù (lìrú yī, èr, sān děng) de wénzhāng. Hángài gèzhǒng shùzì biǎodá fāngshì hé gàiniàn. – This tag gathers articles about cardinal numbers (e.g., one, two, three, etc.). It covers various ways of expressing and concepts related to numbers.)

**Option 3: Focused on Application (if relevant to your content)**

* **Description:** 專注于讨论基數如何应用于日常生活中，例如计数，量度，以及如何在不同的语境中使用。 (Zhuānzhu yú tǎolùn jīshù rúhé yìngyòng yú rìcháng shēnghuó zhōng, lìrú jìshù, liàngdù, yǐjí rúhé zài bùtóng de yǔjìng zhōng shǐyòng. – Focused on discussing how cardinal numbers are applied in daily life, such as counting, measurement, and how to use them in different contexts.)

**Option 4: Simple and General with a Word Count Specification**

* **Description:** 涵盖有关基数的专题文章。 (Hángài yǒuguān jīshù de zhuāntí wénzhāng. – Covering articles on topics related to cardinal numbers.) Word count: approximately 10-20 words.

**What to Choose & Considerations:**

* **Your Content:** Which option best reflects your content’s focus? If you mostly deal with basic counting, option 2 is good. If you use numbers in more applied ways, option 3 might fit.
* **SEO:** While not crucial, using keywords like “numbers,” “counting,” etc. might help. However, the main thing is to be accurate about what the tag covers.
* **Clarity:** Make the description clear to the reader. Ensure it’s easily understandable.
* **Word Count:** Keep it concise but helpful. WordPress won’t limit the length, but a shorter description is usually better.

**How to Input this in WordPress:**

1. **Go to your WordPress admin panel.**
2. **Go to Posts > Tags.**
3. **Find the “基數” tag.** (If you’re adding it, fill in the name field as “基數”.)
4. **In the “Description” box,** paste your chosen description from above.
