I'm wondering what the required qualities of 'being smart' are? Can Grigori Perelman be considered smart? He's definitely unable to plan complex schemes like HR could nor he's able to figure out other people's plots like ZM did, some even think that he's a nerdy idiot, but the fact is that when it comes to IQ he omgwtfpwns all characters in JY's novels. I disagree with the statements that ZM is the smartest character in HSDS. That title should belong to ZWJ. Granted he was toyed around like a kid by the hot chicks in HSDS, however this wimpy dude also showed that his brainpower was at a very high level when he mastered all Hu Qingniu's knowlegde on medicine in just 3 or so years. He could understand complicated martial arts in very short periods of time as well.
