We all know who Guo Xiang is. She's the most talented daughter of the Great Eagle Shooting Hero couple Guo Jing and Huang Rong. Guo Jing is considered as one of the most talented (if not the best because of GJ vs. YG arguments) and powerful fighters in the entire Condor Trilogy and Huang Rong is perhaps the most intellegent fighter herself, not to mention she's the best cook.
Guo Xiang herself is probably one of the most underrated Martial Arts prodigies in the Condor Trilogy. She obviously the most talented among her siblings. She founded E Mei School of Kung Fu which was one of the most prominent in the HSDS period. She roamed Jiang Hu from South to North, East to West in a search for the The One Armed Condor Hero, Yang Guo. Though unsuccesfully, we can definitely assume that she met thousands of fighters during her journeys and thus, she survived and founded E Mei.
In the beginning of HSDS, GX has shown tremendous talent and marvellous knowledge of techniques from numerous Kung Fu schools. We can probably assume during her lifetime, she mastered all of Peach Blossom Kung Fu, parts and bits of Beggar Clan techniques (including Dog Beating techniques), Some understanding of Yi Deng's 1YZ, Maybe some of Guo Jing's Vacant Fist or L-R Technique, maybe some Quan Zhen techniques, some techniques from the Condor couple (YG and XLN) perhaps some parts of 9-Yin, and definitely parts of 9-Yang.
Thus, several questions are yet to be answered (with speculation) :
1) Is there enough facts to say that Guo Xiang perhaps the only person in the entire Condor Trilogy who has been exposed to both 9-Yin and 9-Yang ?
2) Being a Martial Arts prodigy, is it safe to say that during her era, after she founded E Mei, at her peak, she's probably could be considered as one of the Greats herself, along with ZSF.
3) We always talks about Lin Chao Ying being great and all, but the truth is, even her techniques were defeated by 9-Yin. Guo Xiang had exposure (perhaps) to 9-Yin from her parents, and the Condor Hero couple, not to mention she created her own E Mei style. Thus, shouldn't (with some speculation) Guo Xiang perhaps be the best female prodigy in the Condor Trilogy ?
3) And the final question, How great was Guo Xiang at her peak ?
