According to the [Hugo Lookup Order](https://gohugo.io/templates/lookup-order/):

1. layouts/aaa/single.html.html
2. layouts/aaa/single.html
3. layouts/\_default/single.html.html
4. layouts/\_default/single.html

Btw, do you specify the `layout` in front matter?

</div>

This is a leaf bundle, not a section, so without `layout` or `type` in front matter the lookup order is:

1. layouts/page/single.html (applies to all single pages in content root)
2. layouts/\_default/single.html

If you set `type` in front matter to `about`, the lookup order becomes:

1. layouts/about/single.html
2. layouts/\_default/single.html

Thank you for your reply! I already know that index.md is just a regular page, and the template it uses is single.html or single.html.html

Now I find that after there is an index.md file in the aaa/ directory, if I add other articles such as: bbb.md, it will not be able to open. Is it true that as long as there is index.md, other articles cannot be added?

Yes. I just answered this question, again, in another thread:

> Use an \_index.md file to tell Hugo, “This directory is a section (branch bundle) that (probably) has member pages or subsections.” Use an index.md file to tell Hugo, “This is a just a page (leaf bundle), and it has no descendants.”
