What is the origin of Lizhuang white cake?

The main ingredient of Lizhuang white cake is high-quality glutinous rice, which is fried and cooked, and then some Chinese herbal medicines, such as yam, are added to help digestion. And then grinding into fine powder, adding white sugar, and then pressing and molding with a mold. If you add fried and ground sesame seeds, it is called "sesame cake". Both white cakes and sesame cakes are sweet and soft, especially suitable for the elderly and children. I bought a box of Zhuanglibai cake to visit relatives and friends, which is really a unique gift.
