There is this story about the moon-cake. during the Yuan dynasty China was ruled by the Mongolian people. Leaders from the preceding Sung dynasty were unhappy at submitting to the foreign rule, and set how to coordinate the rebellion without being discovered. The leaders of the rebellion, knowing that the Moon Festival was drawing near, ordered the making of special cakes. Backed into each moon cake was a message with the outline of the attack. On the night of the Moon Festival, the rebels successfully attached and overthrew the government. Today, moon cakes are eaten to commemorate this legend and was called the Moon Cake.
For generations, moon cakes have been made with sweet fillings of nuts, mashed red beans, lotus-seed paste or Chinese dates(枣子), wrapped in a pastry. Sometimes a cooked egg yolk can be found in the middle of the rich tasting dessert. People compare moon cakes to the plum pudding and fruit cakes which are served in the English holiday seasons.
Nowadays, there are hundreds varieties of moon cakes on sale a month before the arrival of Moon Festival.
Mooncakes are to Mid-Autumn Festival what mince pies are to Christmas. The seasonal round cakes traditionally have a sweet filling of lotus seed paste or red bean paste and often have one or more salted duck eggs in the center to represent the moon. And the moon is what this celebration is all about. Mid-Autumn Festival falls on the 15th day of the 8th month, it is the time when the moon is said to be at its brightest and fullest. This year the festival falls on October
There are two legends which claim to explain the tradition of eating mooncakes.
One Tang Dynasty myth holds that the Earth once had 10 suns circling it. One day all 10 suns appeared at once, scorching the planet with their heat. It was thanks to a skillful archer named Hou Yi that the Earth was saved. He shot down all but one of the suns. As his reward, the Heavenly Queen Mother gave Hou Yi the Elixir of Immortality, but she warned him that he must use it wisely. Hou Yi ignored her advice and, corrupted by fame and fortune, became a tyrannical leader. Chang-Er, his beautiful wife, could no longer stand by and watch him abuse his power so she stole his Elixir and fled to the moon to escape his angry wrath. And thus began the legend of the beautiful woman in the moon, the Moon Fairy.
The second legend has it that during the Yuan Dynasty, an underground group led by Zhu Yuan Zang was determined to rid the country of Mongolian dominance. The moon cake was created to carry a secret message. When the cake was opened and the message read, an uprising was unleashed which successfully routed the Mongolians. It happened at the time of the full moon, which, some say, explains why mooncakes are eaten at this time.
