The site looks ugly and there is no explanation of what it is all about.
You need to capture your visitors attention straight away or they will go elsewhere.
Design looks so big and not visually appears good as well. Try to small the fonts and arrange it properly. Try to add some boxes for each section. Hope this will help it !!
I have never heard of sites like this before, thanks to sandyk3 for pointing to thebigwordproject, they explain what the sites for, didn't have a clue what your site was about yangyang, I agree with everyone else but would also add that it needs some sort hint at what the site does (if it is in there it was swallowed up by ecerything else)
