Google Blogoscoped’s blog post shows you where to find Google’s Wonder Wheel. The Wonder Wheel appears on Google.cn within the side bar that expands to the left.
For example, my core keyword is “English” (in Chinese) which I have entered into Google’s web search. Google’s Wonder Wheel shows a clickable flash-based image with your core keyword in the center and related keywords around the core keyword.
When I click on one of the related keywords “English Learning” (in Chinese), this keyword gets moved to the center and becomes the new core keyword. It creates a newly connected circle for “English Learning” with new related keywords around this new core keyword.
You can build up your Chinese keyword lists by exploring all the related keywords surrounding the core keywords.
