Here are a few options for a WordPress post_tag description for the title “估算” (Gūsùan) in Traditional Chinese, along with explanations to help you choose the best fit:

**Option 1 (Focus on the Process):**

* **Description:** 用於標記相關文章，這些文章探討了如何進行估算、預測，並提供具體的分析方法。涵蓋範圍廣泛，包含時間、成本、數量等等。 (Yòng yú biāojì xiāngguān wénzhāng, zhèxiē wénzhāng tàn tǎo le rúhé jìnxíng gūsùan, yùcè, bìng tígōng jùtǐ de fēnxī fāngfǎ. Hánguài fànwéi guǎngfàn, bāohán shíjiān, chéngběn, shùliàng děngděng.)
* **Translation:** Used to tag related articles that explore how to perform estimations, predictions, and provide specific analysis methods. The scope is broad, including time, cost, quantity, etc.
* **Why it works:** Directly explains what the tag encompasses. It’s clear and informative, letting readers know what to expect from posts tagged with “估算.”

**Option 2 (Focus on the Result):**

* **Description:** 針對涉及預算、數量、或值判斷的文章設定。 標籤下的文章可能提供估算的範例、技巧，或是對不同估算方法的討論。 (Zhēnduì shèjí yùsuàn, shùliàng, huò zhí pànduàn de wénzhāng shèdìng. Biāojiān xià de wénzhāng kěnéng tígōng gūsùan de fànlì, jīqiǎo, huò shì duì bùtóng gūsùan fāngfǎ de tǎolùn.)
* **Translation:** Created for articles related to budgeting, quantities, or evaluating values. Articles tagged with this may provide estimation examples, techniques, or discussions of different estimation methods.
