Here are a few options for describing the WordPress post_tag “投資所得” (Investment Income) in Traditional Chinese, ranging from concise to more descriptive:

**Option 1 (Concise):**

* **Description:** 投資相關收益的標籤，包括股票、債券、房地產等。 (Tag for investment-related income, including stocks, bonds, real estate, etc.)

**Option 2 (Slightly More Descriptive):**

* **Description:** 此標籤涵蓋了各種投資活動所產生的收益，例如股息、利息、租金以及買賣獲利。 (This tag covers income generated from various investment activities, such as dividends, interest, rent, and capital gains.)

**Option 3 (More Detailed):**

* **Description:** 標記與投資相關的收入。這包括但不限於：股票收益、債券利息、房地產租金收入、共同基金收益、以及外匯交易獲利。此標籤旨在幫助讀者快速篩選與投資收入相關的文章和資訊。 (Tag for income related to investments. This includes, but is not limited to: stock dividends, bond interest, real estate rental income, mutual fund returns, and foreign exchange trading profits. This tag is designed to help readers quickly filter articles and information related to investment income.)

**Option 4 (For SEO, including keywords):**

* **Description:** 投資所得、股息、利息、租金收入、資本 gains、交易獲利相關標籤。了解股票投資、債券投資、房地產投資、共同基金及其他投資工具的收益。 (Tag related to investment income, dividends, interest, rental income, capital gains, and trading profits. Learn about income from stock investments, bond investments, real estate investments, mutual funds and other investment tools.)

**Explanation and Considerations:**

* **”投資相關收益” / “相關的收入” (Related Income):** This is a direct translation of “Investment Income,” making it clear what the tag signifies.
* **Types of Investment:** Mentioning specific examples (stocks, bonds, real estate, etc.) helps readers understand the scope of the tag. Consider the specific types of investments that your blog covers.
* **Keywords:** Use keywords like “股息” (dividends), “利息” (interest), “租金收入” (rental income), “資本 gains” “交易獲利” (capital gains/profits from trading) if you want to help it with SEO.
* **Target Audience:** Adjust the level of detail based on the expected knowledge level of your readership.
* **Readability:** Use clear and concise language. Avoid overly technical jargon unless your audience is well-versed in finance.
* **Purpose:** Remind readers why the tag is used (to quickly find articles about income)

I recommend using Option 3 or 4 as they are the most informative and contribute to SEO, while also explaining the use of the tag. Choose the one that provides the most clarity based on the topics commonly covered in your WordPress posts. Remember to use `traditional Chinese characters.`
