With the continuous development of society, the ancients endowed the moon with many legends, from the toad on the moon to the jade rabbit, from WU GANG to the Goddess Chang'e flying to the moon, and the rich imagination painted a colorful scene for the moon palace world. From the Han Dynasty to the Tang Dynasty, poets and poets praised the moon and its events, and the full moon on August 15 became an excellent moment to express their feelings.
During the reign of Emperor Taizong of the Northern Song Dynasty, August 15 was officially designated as the Mid-Autumn Festival, which was originally intended to be in the middle of Sanqiu, and the whole people would celebrate it then. On the night of Mid-Autumn Festival, the bright moon is in the sky, and the light is scattered all over the earth. People regard the full moon as a symbol of reunion, and August 15 is the day for family reunion. Therefore, Mid-Autumn Festival is also called "Reunion Festival".
Mid-Autumn Festival has become an important festival in a year, which has a very subtle relationship with the imperial examination. In China's feudal society, it has always been a major event that rulers attach great importance to. The triennial autumn competition has just been scheduled for August.
When scenery and passion are combined, people will regard the person who took the senior three exam as the person who won the laurel in the middle of the month. It has become an important custom of the whole society to celebrate the Mid-Autumn Festival. From generation to generation, Mid-Autumn Festival has gradually become one of the four major festivals in China (Spring Festival, Tomb-Sweeping Day, Dragon Boat Festival and Mid-Autumn Festival).
