When math meets the Mid-Autumn Festival, hand-written newspaper.

First, the source of Mid-Autumn Festival

The Mid-Autumn Festival originated in ancient times, popularized in the Han Dynasty and shaped in the Tang Dynasty. Mid-Autumn Festival is a synthesis of autumn seasonal customs, most of which have ancient origins. As one of the important customs of folk festivals, offering sacrifices to the moon has gradually evolved into activities such as appreciating and praising the moon. The Mid-Autumn Festival is a colorful and precious cultural heritage. The full moon is a symbol of people's reunion, a sustenance for missing their hometown and relatives, and hopes for a bumper harvest and happiness.

Second, the story about Mid-Autumn Festival.

On the night of Mid-Autumn Festival, the moonlight is bright. The ancients regarded the full moon as a symbol of reunion, so August 15 was also called "Reunion Festival". Throughout the ages, people often use "full moon" and "lack of moon" to describe the "joys and sorrows" of wanderers living in other places, and also to pin their affection for the moon. Li Bai, a poet in the Tang Dynasty, wrote poems such as "Looking up, it's moonlight, then leaning back, suddenly thinking about hometown", "Knowing that the dew is frost tonight, the moonlight at home is bright!" Du Fu's "Spring Breeze is Green in Jiang Nanan" and Wang Anshi's "When Will the Moon Shine on Me" in the Song Dynasty are all timeless masterpieces.

Mid-Autumn Festival, Lantern Festival and Dragon Boat Festival are also called the three traditional festivals in China. Investigating the origin of the Mid-Autumn Festival is closely related to myths and legends such as "the Goddess Chang'e flying to the moon", "Wu Gang cutting Guangxi" and "Jade Rabbit smashing medicine". Therefore, the folk customs of Mid-Autumn Festival are mostly related to the moon. Watching the moon, Yue Bai and eating reunion moon cakes all originated from this. Ancient emperors had a social system of offering sacrifices to the moon in spring, and folks also had the custom of offering sacrifices to the moon in the Mid-Autumn Festival. Later, it was more important to enjoy the moon than to sacrifice it, and serious sacrifice turned into light entertainment. The custom of enjoying the moon in the Mid-Autumn Festival prevailed in the Tang Dynasty, and many poets wrote poems about the moon in their masterpieces. In the Song, Ming and Qing Dynasties, Yue Bai's court and folk activities to enjoy the moon were even larger. So far, there are many historical sites in China, such as Yue Bai Altar, Moon Pavilion and Moon Tower. The "Moon Altar" in Beijing was built during the Jiajing period of the Ming Dynasty, and was used for royal sacrifice to the moon. Whenever the moon rises in the Mid-Autumn Festival, a box is set up in the open air, with moon cakes, pomegranates, dates and other fruits on the console table. After Yue Bai, the family sat around the dining table, chatting while eating and enjoying the bright moon. Now, the activities of offering sacrifices to the moon in Yue Bai have been replaced by large-scale and colorful activities of enjoying the moon by the masses.

Three. Poems about Mid-Autumn Festival

1、

Watching the moon in the Mid-Autumn Festival in Yangguan District? Su Shi

Clouds at dusk are full and cold. Han Yin silently turned to the tracts.

If you don't meet a good night in this life, where will you see the bright moon next year?

2、

Watching the moon at the basin pavilion on the night of August 15th? Bai Juyi

On the evening of August 15 last year, next to the apricot garden by Qujiang Pool.

On the night of August 15 this year, in front of the Shuige in Shatou, Wenpu.

Where is the hometown in the northwest and the full moon in the southeast.

Yesterday, the wind blew and no one would meet. Tonight, the light is as clear as usual.
