multi site : post top sub 3 posts on main site (1 post)

I have a multi site.

Main site, sub site.

As you know, these 2 sites have each tables. wp_posts and wp_2_posts...etc

I need to put top 5 new posts(sub site) on main page of main page of Main site.

Any advice?

I know how to do php, sql briefly. "select............from...."

but not sure where I should put...the php select codes...

Thanks,
