The Koreans use wooden poles and pine boughs to build a "moon watch stand". When the moon rises in the sky, they invite a number of selected elderly people to climb up to it. After the old men look at the moon, they light up the frame, play long drums and dongxiao, and dance the "Nongjiale Dance" together.
The Mid-Autumn Festival has been practiced since ancient times, with customs such as sacrificing to the moon, enjoying the moon, worshipping the moon, eating mooncakes, enjoying osmanthus flowers, and drinking osmanthus wine, which have been passed down to the present day and are still uninterrupted. The Mid-Autumn Festival has become a colorful and precious cultural heritage, with the fullness of the moon signifying the reunion of people, as a token of longing for one's hometown and relatives, and praying for a good harvest and happiness. The Mid-Autumn Festival, together with the Dragon Boat Festival, Spring Festival and Ching Ming Festival, are known as the four major traditional festivals in China.
