Because Yue Fei was killed by Qin Hui at that time, their statues were opposite Yue Fei. People hated Qin Hui deeply, but there was nothing they could do about it (because Qin Hui was dead.) So the locals rolled flour into a human figure to represent Qin Hui, and put "Qin Hui" into a pot and fried it. Later, people found it troublesome, so they just made it into strips and fried it in a pot to relieve their hatred. This is the relationship between Youtiao and Yue Fei.
