Why google can't find my personal blog?

Well, I've developed a website xudongshao's website based on hexo

And according to some tutorials I've set the sitemap and so on. But it seems that only if I search the content of my blog, that I can find my post. If I search the title, in this case, is the "Malware analysis: GINA interception", it shows no results. I really don't know why. enter image description here
