During the spring festival I tend to have far too much time on my hands. I decided to refresh on using JavaScript and XML. So an afternoon of playing around yielded this website.

Your objective is to guess what word the riddle谜语 is referring to. The answers aren't complex words and usually fall into the categories of food, animals, professions and so on.
It only accepts simplified character input (not pinyin). You can use the hint button to reveal the category or the "I don't know!" button to get the answer.
Good luck!
