Here are a few options for a WordPress post_tag description, in traditional Chinese, for the title “費用資訊” (Fèi Yòng Zī Xùn – Cost Information), with varying levels of detail and emphasis:

**Option 1: Concise and Direct**

> 匯集所有與費用相關的資訊，包括價格、開支、預算等。
> (Huìjí suǒyǒu yǔ fèiyòng xiāngguān de zīxùn, bāokuò jiàgé, kāizhī, yùsuàn děng.)
> *Translation: Gathers all information related to costs, including prices, expenses, and budgets.*

**Option 2: Slightly More Explanatory**

> 探索有關產品、服務或其他項目之費用、成本、價格的資訊，讓您清晰了解所需花費。
> (Tànsuǒ yǒuguān chǎnpǐn, fúwù huò qítā xiàngmù zhī fèiyòng, chéngběn, jiàgé de zīxùn, ràng nín qīngxī liǎojiě suǒ xū huāfèi.)
> *Translation: Explore information about the costs, expenses, and prices of products, services, or other items, allowing you to clearly understand the required spending.*

**Option 3: Focusing on Clarity and Transparency**

> 此標籤涵蓋所有關於費用的明細，旨在提供清晰透明的價格資訊，讓您做出明智的決策。
> (Cǐ biāoqian hánggài suǒyǒu guānyú fèiyòng de míngxì, zhǐzài tígōng qīngxī tòumíng de jiàgé zīxùn, ràng nín zuòchū míngzhì de juécè.)
> *Translation: This tag covers all details about costs, aiming to provide clear and transparent pricing information, allowing you to make informed decisions.*

**Option 4: For a specific context (e.g., a blog about Travel)**

> 關於旅行、機票、住宿、活動等相關的費用資訊，包括價格、優惠、比價等，幫助您規劃更划算的旅程。
> (Guānyú lǚxíng, jīpiào, zhùsù, huódòng děng xiāngguān de fèiyòng zīxùn, bāokuò jiàgé, yōuhuì, bǐjià děng, bāngzhù nín guīhuà gèng huásuàn de lǚchéng.)
> *Translation: Information about travel, tickets, accommodation, activities, etc., including prices, discounts, and comparisons, to help you plan a more cost-effective trip.*

**Which Option to Choose:**

* **Option 1** is a good general-purpose choice. It’s concise and will work in most contexts.
* **Option 2** is more helpful if the content is quite broad.
* **Option 3** is best if transparency and clear pricing are a key focus.
* **Option 4** is the best choice if your content is specifically oriented towards travel.

When adding the description in WordPress, typically, you would navigate to **Posts > Tags**, then select the specific tag, and enter the chosen description in the “Description” field. Good luck!
