Well, if you Joan of Arc up there, why not Mulan?
Personally, I think the bravest, most courageous and patriotic person in history if Yue Fei.
Yue Fei put duty above everything else, and few people in history have done so much for their country. He had devoted his entire life in fighting against the Jin, the Mongols, and the Jurchen tribes. He fought with valor, demonstrated true leadership, preservered through unimaginable hardship, and stood admant and resolute, unmoving in his cause. He was able to prevail over impossible odds in nearly god-like feats of generalship and martial prowess. Furthermore, rather than betraying his country or saving his own neck, he knowingly walked to his own death when his execution was ordered by the despicable traitors to the Chinese people.
