Well, I could name (again) the video game where I originally learned it, but as I've already made clear, video games aren't really a reliable source. If you'd like to see a source solely for verification... http://en.wikipedia.org/wiki/Four_Symbols_(China)  However, wikipedia is not technically a reliable source, either. It's what's known as a secondary source. While its accuracy is debatable in some cases, it can be trustworthy on an individual basis... I actually don't have a primary source right now (that is, one that I can truly call reliable) to either direction, so this is the closest you're going to get. (A primary source is a source which cannot be publicly edited and is generally relied upon to have factual information such as an encyclopedia or an educational website.)  Feel free to provide a primary source or a secondary source of equal status if you'd like me to eat my words.
