It's beyond words to establish a comments system all by oneself. 啥也不说了，做一个博客评论系统太他喵的难了。。。
It's really really complex to build a comments system all by oneself. I finally understand why so many people, although who is very familiar with building a website, use the third party comments system, such as Disqus!.
While at the same time, I feel quite happy that I can make such one, one small step after another from Level ERO, even I knew nothing about any terms in Web Building several days ago. Although it cost me about 3 BIG days since it's only 94 days before the 2013 Postgraduate Admission Test, which will be on Jun 5^th^, 2013. So after this important step, I will pay more attention to prepare for the BIG TEST. Then I will come back!
