How do I stop the Hero Content from being centered?

Hi, My website is www.jinnzhong.com. I just have a quick question. How do I stop my bio in the "hero content section" on my front page from being centered? It's not centered on the actual page: http://www.jinnzhong.com/about/ But it is as "hero content" on the front page: http://www.jinnzhong.com/#section1 Thank you.
