**How to Implement in WordPress:**

1. **Go to:** Your WordPress dashboard > Posts > Categories or Tags (depending on how you’re organizing your content. Tags are generally better for this purpose.)
2. **Create a New Tag (If it doesn’t already exist):** Under Name, enter “常數表”. Under Slug (which you should usually leave WordPress to fill in automatically). Under “Description” paste or type your chosen description (from one of the options above or adapted to suit).
3. **Update:** Save the tag.

Remember to use the chosen description consistently with all the posts you tag with “常數表”.
