Light cakes are one of the traditional snacks in Fuzhou, and Fuzhou people like to eat light cakes. In many alleys of Fuzhou, you can often see some small shops. The bread is about the size of a cup, about two centimeters thick, with a yellow surface and many sesame seeds embedded in it. The cake is recessed in the middle, revealing a small pit. Press it hard with your hand. This is a light cake. Its name is related to the legend that Qi Jiguang entered Fujian to resist Japan. It is reported that during the Jiajing period of the Ming Dynasty, invaders invaded the coastal areas of Fujian, and Qi Jiguang ordered Qi Jiajun to enter Fujian to fight against the Japanese aggressors. At that time, the Japanese army was rampant and the war continued, and the people along the way rushed to reward the three armed forces. However, Qi Jiajun had strict military discipline and did not accept gifts. People in the Qing Dynasty specially made a kind of cake with a hole in the middle, strung it with bittern grass and hung it around the necks of soldiers of the Qijiajun. Qi Jiguang was deeply moved by the people's love for the army. Seeing that the army also needed light dry food, he accepted the people's wishes. After the news reached Fuzhou, the local people made a cake smaller and more portable than Minqing cake, and put it on with a string and gave it to Qi Jiajun. Qi Jiguang saw that this kind of cake was very practical in battle, so he asked the leader to make it like this. Later, in order to commemorate Qi Jiguang's anti-Japanese war, people called cookies "light cakes" and cakes "east cakes". Light cakes are deeply loved by Fuzhou people. Ancient literati liked to eat light cakes. When people who go to Beijing to take the exam pass through Fuzhou, they should buy a lot of light cakes for dry food on the way. Over time, how many light cakes they ate became synonymous with measuring the children's efforts.
