Eat with the concept of health preservation. Bazhen cake is a dietetic prescription of traditional Chinese medicine, which is divided into "eight treasures for men" (used as "eight treasures for men" in Qianlong) and "eight treasures for women" (used as "eight treasures for women" by Cixi). "Men's Eight Treasures" are the original eight-treasure cakes, which are divided into two types: invigorating spleen, eliminating food stagnation and invigorating vitality.
