Get page cross multisite?

Hello,

I setup multisite with sub-folder as follow:
user/sites/blog

I want to get last 3 posts from user/sites/blog/pages/posts/, and list them on the main site.
Is’t possible?

Thanks
Lei

Any hint?

Sorry not really following the details of your questions. Maybe hop on slack and ask there? That way it can be a more interactive conversation. Cheers.
