Okay, here are a few options for describing the WordPress post_tag “how much does it cost” in Traditional Chinese, along with explanations:

**Option 1 (Most Direct and Common):**

* **Title (Post Tag):** “how much does it cost”
* **Description:** **費用 (fèi yòng)** – *This is the most straightforward and common translation for “costs” or “expenses” in general.*

**Explanation:**

* **費用 (fèi yòng):** This is the most universally understood and accepted term. It covers a wide range of costs, making it adaptable to different contexts.

**Option 2 (More Emphasizing Price):**

* **Title (Post Tag):** “how much does it cost”
* **Description:** **價格 (jià gé)** – *This focuses specifically on the price or price tag of something.*

**Explanation:**

* **價格 (jià gé):** Directly translates to “price” and is suitable when dealing with the cost of specific items or services.

**Option 3 (More General Cost related):**

* **Title (Post Tag):** “how much does it cost”
* **Description:** **成本 (chéng běn)** – *This word can translate to “cost” or “expense.*

**Explanation:**

* **成本 (chéng běn):** Directly translates to “cost” or “expense”.

**Considerations when Choosing:**

* **Context of Your Content:** The best choice depends on the content of the posts using this tag.
* If your posts are primarily about the cost of things in general, “費用 (fèi yòng)” is a safe bet.
* If your posts mainly address the prices of specific items, “價格 (jià gé)” is more targeted.
* If your posts are about production cost, “成本 (chéng běn)” would be a more appropriate.

I recommend using the first option (“費用”) as it’s the most versatile and easily understood for most readers. You can change the description at any time if your content’s focus shifts.

Good luck with your WordPress site!
