According to the music education and research network, Wei Jiguang, an anti-Japanese national hero, led his troops to hunt down the ambassador in Fuqing Tian Niu (now Longtian). In order to reduce the cooking time, Qi Jiguang arranged two kinds of round cakes made of flour for charcoal fire moxibustion. In memory of Qi Huangong, people in Fuqing, Fuzhou and Minqing copied these two kinds of round cakes, which are called "light cakes". Later, someone added sesame seeds to the sesame seed cake, which became "sesame seed cake", also called "Fuqing cake".
