Here are a few options for the post tag description, reflecting different approaches:

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

* **Description:** 簽名 (Qiānmíng). This tag encompasses posts related to signatures, autograph, or signing documents.

**Option 2: More Descriptive (For Contextual Understanding)**

* **Description:** 本標籤收錄與「簽名」有關的內容，涵蓋親筆簽名、數位簽名、簽署文件等不同主題。 (Běn biāoqiān shōulù yǔ “qiānmíng” yǒuguān de nèiróng, hángài qīnbǐ qiānmíng, shùzì qiānmíng, qiānshǔ wénjiàn děng bùtóng zhǔtí.) – This tag includes content related to “signatures,” covering handwritten signatures, digital signatures, signing documents, and other related topics.

**Option 3: Focusing on Usage (Especially useful if posts discuss actions)**

* **Description:** 此標籤標示與簽署、蓋章等行為相關的文章，涵蓋同意、授權、確認等含義。 (Cǐ biāoqiān biāoshì yǔ qiānshǔ, gàizhāng děng xíngwéi xiāngguān de wénzhāng, hángài tóngyì, shòuhuà, quèrèn děng hányì.) – This tag marks articles related to signing, sealing (stamps), and related actions, covering meanings like agreement, authorization, and confirmation.

**Option 4: Targeting a Specific Audience**

* **Description:** 法律文件、合約等涉及簽名程序之文章，皆適用此標籤。 (Fǎlǜ wénjiàn, héyuē děng shèjí qiānmíng chéngxù zhī wénzhāng, jiē shìyòng cǐ biāoqiān.) – This tag is applicable to articles related to the signature process of legal documents, contracts, etc.

**How to Choose:**

* **Consider the content of your posts:** If your posts primarily discuss the *act* of signing, Option 3 is good. If you discuss different *types* of signatures, Option 2 is solid. The simplest is option 1.
* **Target audience:** If your blog is legal-focused, option 4 is better
* **Keep it concise:** WordPress tag descriptions don’t need to be long. Simple and informative is best.

I’d suggest starting with Option 1 or 2 (the simpler of the two), as those will work for a wide range of content. You can always refine it later if you decide you want greater specificity. Remember to insert the description when you create or edit the tag in your WordPress admin area.
