Unable to embed html file in the post

[Mingzhi]

Hi there,

Thanks for sharing your great work. I have a question in how to embed the HTML file in the post markdown file?

I upload the HTML file to _include folder, and use {% include newyork_map.html %} in the post markdown file.

But it does not show up in my post, just display the plain text '' .

Any way to solve it? Thanks!
