History
The Mid-Autumn Festival celebrations date back to more than 2,000 years ago. In feudal times, Chinese emperors prayed to Heaven for a prosperous year. They chose the morning of the 15th day of the second lunar month to worship the sun and the night of the 15th day of the eighth lunar month to hold a ceremony in praise of the moon. In the western district of Beijing is the Yuetan Park, which originally was the Temple of Moon, and every year the emperor would go there to offer a sacrifice to the moon.

This ancient custom became prevalent in the Tang Dynasty (618-907) that people enjoyed and worshipped the full moon. In the Southern Song Dynasty (1127-1279), however, people sent round moon cakes to their relatives as gifts in expression of their best wishes of family reunion. When it turned dark, they gazed up at the full silver moon or went sightseeing by lakes, to celebrate the festival.

Since the Ming (1368-1644) and Qing dynasties (1644-1911), the custom of Mid-Autumn Festival celebration has become unprecedentedly popular. Together with the celebration appeared some special customs in different parts of the country, such as burning incense, planting Mid-Autumn trees, lighting lanterns on towers and fire dragon dances, etc. Whenever the festival sets in, people would look up at the full silver moon, drinking wine to celebrate their happy life, or thinking of their relatives and friends far from home and extending all of their best wishes to them.

In mid-autumn, farmers have just finished gathering their crops and bringing in fruits from the orchards. They are overwhelmed with joy when they have a bumper harvest and at the same time, they feel quite relaxed after a year of hard work. So the 15th day of the eighth lunar month (the Mid-Autumn Festival) has gradually evolved as a widely celebrated festival for ordinary people.

The Moon FairyLady - 'Chang Er'
In fact, many ancient August Moon folktales are about a moon maiden. On the 15th night of the 8th lunar moon, little children on earth can see a lady on the moon.

The story about the lady takes place around 2170 B.C. At that time, the earth had ten suns circling it, each taking its turn to illuminate to the earth. But one day all ten suns appeared together, scorching the earth with their heat. The earth was saved by a strong and tyrannical archer named Hou Yi. He succeeded in shooting down nine of the suns. One day, Hou Yi stole the elixir of life from a goddess. However, his beautiful wife Chang E drank the elixir of life in order to save the people from her husband's tyrannical rule. After drinking it, she found herself floating and flew all they way to the moon. Hou Yi loved his divinely beautiful wife so much, he refused to shoot down the moon.

People believed that the lady was a god who lived in the moon that made the moon shine. Girls who wanted to be a beauty and have a handsome husband should worship the moon. And on this magical occasion, children who make wishes to the Lady on the Moon will find their dreams come true.

The wood cutter - Wu Kang
Wu Kang was a shiftless fellow who changed apprenticeships all the time. One day he decided that he wanted to be an immortal, so he went to live in the mountains where he importuned an immortal to teach him. First the immortal taught him about the herbs used to cure sickness, but after three days his characteristic restlessness returned and Wu Kang asked the immortal to teach him something else. So the immortal to taught him chess, but after a short while Wu Kang's enthusiasm again waned. Then Wu Kang was given the books of immortality to study. Of course, Wu Kang became bored within a few days, and asked if they could travel to some new and exciting place. Angered with Wu Kang's impatience, the master banished Wu Kang to the Moon Palace telling him that he must cut down a huge cassia tree before he could return to earth. Though Wu Kang chopped day and night, the magical tree restored itself with each blow, and thus he is up there chopping still.
