Crullers,is a traditionalstaple food, long hollow fried snacks with a crispy yet chewy texture, one of the traditionalmornings for breakfastin China.Many people mistakenly believe that during the Song Dynasty, when Qin Hui persecuted Yue Fei, the people expressed their anger by frying a type of face-shaped food (Oil Fried Cui) akin to crullers, which is considered the origin of crullers; in reality, crullers predate the Song Dynasty.The exact period remains unverifiable.As early as the Northern and Southern Dynasties era,the agricultural scientist Jia Sixie documented methods for making fried foodsin his work "Qimin Yaoshu"."With delicate hands, they roll out strips of white dough; deep-fried in green oil, they turn a tender golden hue. Night brings the spring air, and beauties wrap them around their arms."
