The Chinese Moon Festival usually takes place on the 15th day of the eight lunar month (in September or October). The Mid-Autumn Festival is held in honour of the Moon Goddess which is believed to have been born on this date.
Besides these historical facts, there are also many myths and legends, one of these is that of Siang-Ngor (Some says Chang-E) Siang-Ngor was very beautiful. She was the wife of a high-ranking Chinese officer. After taking a magic medicine, she flew up to the moon and lived there. She later became immortal after consuming the immortal water given to her by a certain Goddess in heaven. Siang-Ngor the Moon Goddess was said to be very kind. When the cultivation season arrived, she would pour immortal water to the earth and this brought prosperity to all farmers. To express their gratitude to the Moon Goddess, farmers thus made Khanom go (or sweetmeat) from rice flour as an offering to her on the full moon night of the eight lunar month.
