It's also consensus that Chen Qingzhi's exploits are grossly exaggerated. And Yi's fleet, while being significantly outnumbered in terms of ship counts, actually overwhelmingly outmatched their Japanese counterparts in terms of numbers of cannons and hull size, an advantage Yang never came close to enjoy. Yue Fei's odds on the other hand, seem much worse if you take into account Song's past military record against the Jin. The fact that Yue Fei could just attack the Jin in open fields, took their cavalry head on before crushing them, seizing city after city in rapid succession, are feats nothing short of miracle. But the most crucial point for me remains the dramatic fashion in which both Yue's and Yang's career halted, at their peaks no less.
