I didn't expect to see such a nice logo from a UK owned website. In the mean time, I'm so proud to realize that Chinese culture has its influence all over the world. (at least I believe so ^^)
This snapshot came from Logoease with online service of logo design. It provides all kinds of collages and fonts for you to composite your logo, and you can easily change the color or layer settings, etc. Most importantly, the service is for free. Here's the link if you wanna try.
There're several other sites provide similar services, and here's another one, logoyes. I really like the sample logos there in the form of letters. But you have to pay to get the finished product.
