**Key Considerations When Choosing:**

* **Target Audience:** Who are you writing for? Bakers, consumers, health-conscious individuals? Tailor the language accordingly.
* **Post Content:** Does the post focus on basic ingredients, health implications, recipes, or something else? The description should reflect that.
* **SEO:** Include relevant keywords to help search engines understand the tag’s topic. “麵粉 (flour),” “酵母 (yeast),” “健康 (health),” and “配方 (recipe)” could be useful.
* **Length:** WordPress allows for a reasonable description length; choose an option that balances being informative without being overly verbose.

I recommend choosing based on the specific focus of your blog and its overall voice. Option 4 is likely the best for SEO if you have the content to support it. Option 1 is great for simplicity.
