The history of Light Cake starts from War of Resistance against Japanese Aggression, Qi Jiguang. According to the Records of Fuzhou Prefecture, in the forty-two years of Jiajing in the Ming Dynasty (1563), Qi Jiguang, an anti-Japanese hero, led an army into Fujian to pursue and annihilate the enemy, and it rained for days, making it impossible for the army to start a business. Qi Jiguang ordered the baking of one of the simplest biscuits and hung them on the soldiers with hemp rope as dry food. Later, this kind of cake flowed into the people, which was not only widely eaten, but also became a necessary offering to worship the ancestors of the gods. Later generations were very sympathetic to Qigong, so they called this biscuit "Jiguang cake". This name is still maintained in Fuan and other places in the province.
