github blog posts not showing

I have created blog using github and it worked fine untill now.
I have uploaded two posts under _posts but it does not show in my blog.
Also, there are three posts in first page of my blog, but they are showing all same posts when I click on them.
I was wondering if there are solutions for my problem. is my blog address.

Hi, @jyeon94!

I’ve just had a look at your published site, as well as your repository, and it looks like the various posts in your _posts folder are now being published successfully.

It seems at least part of the earlier trouble you faced was due to broken symlinks, which you have since resolved:

Nice work! :star2: Let me know if there’s anything else you still need help with.
