Although different parts of China have different ways to celebrate the Mid-Autumn Festival, eating the moon cake remains one of the main activities and is practised by all the Han Chinese. Usually the moon cake is round in shape and is made of sweet lotus seed paste with egg yolks inside. Obviously, the egg yolk represents the moon. There are also other flavors to choose from such as sesame, almond, walnut kernels, red beans and jujube pastes, etc. Recent years you can see also ice cream moon cakes. Sending moon cakes as festive presents is common among the Chinese people, even businessmen.
