Here are a few options for describing the “返利” post tag in Traditional Chinese, ranging in formality and emphasis:

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

> 關於返利的相關文章。 (Guān yú fǎn lì de wénzhāng. – Articles about cashback.)

**Option 2 (Slightly Expanded & Explanatory):**

> 包含返利資訊、購物優惠、現金回饋等相關主題的文章標籤。 (Bāohán fǎn lì zīxùn, gòuwù yōuhuì, xiànjīn huíkuì děng xiāngguān zhǔtí de wénzhāng biāoqiān. – Article tag including information about cashback, shopping discounts, and cash rewards.)

**Option 3 (Emphasis on Benefits):**

> 探索各種返利管道、尋找省錢妙招，讓您購物更划算！ (Tànsuǒ gèzhǒng fǎn lì guǎndào, xúnzhǎo shěngqián miàozhāo, ràng nín gòuwù gèng huásuàn! – Explore various cashback channels and discover money-saving tips to make your shopping more worthwhile!)

**Option 4 (More Technical & Targetted):**

> 針對電商返利、信用卡回饋、網站比價等相關主題的標籤。 (Zhenduì diànshāng fǎn lì, xìnyòngkǎ huíkuì, wǎngzhàn bǐjià deng xiāngguān zhǔtí de biāoqiān. – Tag focused on e-commerce cashback, credit card rewards, and website price comparisons.)

**Which option to choose depends on:**

* **Your audience:** Are you targeting beginners or experienced shoppers?
* **The content of your blog:** Does it focus on specific areas of cashback?
* **SEO:** Consider keywords your target audience might search for.

For general use, **Option 2** is likely a good balance of clarity and information. You can adjust it based on your specific needs. Remember to keep it relatively short and descriptive for optimal use within WordPress.
