I know this sounds stupid, but where is the red heart? i can't seem to find it in any of the posts at all...

it is at the upper right corner. You can find it in any post.

2 hearts with chinese letters

I believe that if you look more carfully, you should see it easy.

right on the top, with a small red pic, hehe, have fun

two hearts one big one with a small one on top to the lower right pic, its not hard to miss
