How to display post description in post grid on Blogger homepage?

问题

I want to display the description of the post in the post grid displayed on the homepage but I don't know which data tag to use correctly. I tried using <data:blog.metaDescription/> but it belongs to the description of the page. I have also tried using <data:post.description/> but the command might be wrong or doesn't exist.

So how to display the description of the post in the post grid?

Do you have any suggestions for me?

Thanks in advance :D
