The Mid-Autumn Festival is an ancient and traditional festival, and worshiping and admiring the moon is also an important custom of the festival. According to legend, ancient emperors had a social system of worshiping the sun in spring and the moon in autumn, and people also had the custom of worshiping the moon in the Mid-Autumn Festival. Later, admiring the moon became more important than worshiping the moon, and the serious worship turned into a relaxed and joyful one. The custom of appreciating the moon during the Mid-Autumn Festival peaked in the Tang Dynasty. Many poets included poems praising the moon in their famous works. In the Song, Ming and Qing dynasties, the activities of worshiping and appreciating the moon among the court and the people became more extensive. There are many ancient monuments such as "Moon Worship Altar", "Moon Worship Pavilion" and "Moon Watching Tower" remaining in various parts of our country. The "Altar of the Moon" in Beijing was built during the Jiajing period of the Ming Dynasty for the royal family to worship the moon. Whenever the moon rises during the Mid-Autumn Festival, a table is set up in the open air, and moon cakes, pomegranates, dates and other fruits are offered on the table. After worshiping the moon, the whole family sits around the table, eats and talks, and enjoys the bright moon. Nowadays, the activities of worshiping and worshiping the moon have been replaced by grand and colorful mass moon-viewing recreational activities.

There is also a legend that after Hou Yi shot down the sun, the Queen Mother gave him a package of elixir. When Hou Yi went hunting, his wife Chang'e accidentally swallowed the elixir and flew to the Moon Palace. Became the master of Guanghan Palace. Because Hou Yi missed his wife Chang'e very much, he set up an incense table in his home, placed her favorite things, and offered sacrifices to Chang'e who was nostalgic for him in the moon palace. After the people heard the news that Chang'e flew to the moon and became an immortal, they all set up incense tables under the moon and prayed to the kind-hearted Chang'e for good luck and peace. From then on, the custom of worshiping the moon during the Mid-Autumn Festival spread among the people. This is why it is necessary to admire the moon during the Mid-Autumn Festival.
