Please help me do some magic with relationship field

Please help me do some magic with ACF relationship field.
I’ve have 400 posts in WordPress and now I want to post same amount of posts in Different CPT (called CANADA) all the specs data is same (so I want to use relationship field that connects one posts and bring all data from there and display in my single-canada.php template same template as post. But I can’t seem to load the relationship field data from the post. Can anyone have idea about this.

So, when I create post in CANADA i just have to select post and all the data should be brought up from post and same design template.
