Guan Yu was delibratelt popped up during the qing dyansty to dilute the sentiment towards Yue Fei. At least to me, in terms of military exploits and personality standing, Yue Fei is sure above Guan Yu

Hanfu advocates usually get their anti-manchu frenzy from movies and are removed from present day chinese situation . Most of them even take the weight of Guan Yu's scimitar literally.
