When you add the description to WordPress, it’s a good idea to keep it concise(under 150 characters is often recommended for SEO purposes). You can choose the one that best fits the content of your blog. You may also want to consider adding relevant keywords like “情緒 (emotions)”, “壓力 (stress)”, “克服 (overcome)”, “快樂 (happiness)” in the description for SEO.
