The origin of the dragon's rise on February 2 nd was called Zhonghe Festival in ancient times, commonly known as the dragon's rise. According to folklore, every second day of the second lunar month is the day when the Dragon King, who is in charge of sex, looks up. After that, the rain will gradually increase. The so-called "dragon heads up" means that after hibernation, all insects begin to wake up. So as the saying goes, "On February 2nd, dragons looked up and scorpions and centipedes appeared." Therefore, this day is also called "Spring Festival". Around the second day of the second lunar month, the earth began to thaw, the weather gradually warmed up, spring returned to the earth, and everything recovered. Insects, snakes and wild animals curled up in mud or caves will wake up from hibernation, and the legendary dragon will wake up from a deep sleep. The farmers bid farewell to their leisure and began to work in the fields. Therefore, in ancient times, "February 2" was also called "the last two days". Therefore, the Spring Festival, which was popular among the people in China, was also called "Spring Farming Festival" in ancient times. It is said that if you don't wake up this day, the rumble of thunder will call it. In the north, February 2 is also known as Dragon Head-Up Day, Spring Dragon Festival and Head-Making Festival. It is widely circulated that "on February 2, the dragon looked up; The big warehouse is full and the small warehouse flows. " Folk proverbs. It was called the picnic festival in the south and the vegetable picking festival in ancient times. According to the climate law, on February 2nd of the lunar calendar, most parts of China were affected by the monsoon climate, and the temperature rose, the sunshine hours increased and the rain gradually increased. The conditions of light, temperature and water can meet the growth of crops, so February 2 is also an agricultural festival in southern rural areas. Since the Tang Dynasty, China people have had the custom of February 2nd. Shen Bang's "Miscellaneous Notes on Ten Thousand Parts" records: "Ten thousand people call the dragon to look up on February 2. The villagers used a euphemistic cloth to enter the kitchen from the outside and circled around the water tank, calling it Longgui. " Ming people Yu Yizheng and Liu Dong said in "A Brief Introduction to the Scenery of the Imperial Capital": "On February 2, the dragon looked up and fried the leftover cakes on the New Year's Day, smoked kang and smoked insects; If you attract a dragon, the bug won't come out. "As the saying goes,' If the dragon doesn't look up, it won't rain'. "The dragon is auspicious and the master of wind and rain." Spring rain is as expensive as oil. "People pray for the dragon to raise its head to make rain and nourish everything. At the same time, around February 2, insects are prone to diseases when they are impacted. In ancient China, people divided organisms into five categories: caterpillars (furry mammals), feather insects (birds), crustaceans (crustaceans), scale insects (scaly fish and winged insects) and humans. Dragons are the length of scale insects. When dragons come out, all kinds of insects hide. Therefore, on the second day of the second lunar month, the dragon looked up, hoping to subdue the insects that were just about to move with Rowen, in order to pray for a bumper harvest in agriculture and the safety of people and animals.

The legend of the Spring Festival is a folk myth in northern China. It is said that Wu Zetian became emperor, which annoyed the jade emperor and told the four dragon kings that it was forbidden to rain on earth for three years. Soon, the Dragon King, who was in charge of Tianhe, heard the cries of the people, saw the tragic sight of people starving to death, and worried that life on the earth would be cut off, so he violated the jade emperor's will and rained for the world. When the Jade Emperor learned that the Dragon King had been knocked down to earth and was crushed under a big mountain to suffer, a monument was erected on the mountain: "The Dragon King's rain violated heaven and should be punished for eternal life; If you want to re-enter the Lingxiao Pavilion, unless the golden beans bloom. "In order to save the Dragon King, people are looking for golden beans in full bloom everywhere. On the second day of the second lunar month, when people are drying corn seeds, they think this corn looks like golden beans. Don't golden beans bloom when they are fried? So every household popped popcorn and put a case in the yard to burn incense for the blooming "Golden Bean". The Dragon King looked up and knew that it was the people who saved it. He shouted to the jade emperor, "The golden beans are blooming, let me out quickly! "When the Jade Emperor saw that the golden beans in the yard of every household in the world were in full bloom, he would send a message to the Dragon King to save the world and continue to have sex with the world. Since then, people have formed a habit of eating popcorn on the second day of February. This folk story of "the integration of heaven and earth" is the crystallization of the wisdom of ancient working people; From another angle, it also reflects the reality that ancient agriculture was restricted by the weather and the farmers' good wishes for good weather and abundant crops. However, according to records, "On February 2nd, the dragon looked up" was related to the understanding of star movement and agricultural solar terms in ancient astronomy. In the ancient astronomical observation model, 28 constellations were determined on the ecliptic on Sunday, which was called 28 nights. The ancients divided these 28 stars into four palaces according to the southeast and northwest, with 7 nights in each palace, and attached these four palaces to four kinds of animals according to their images. Among them, the seven nights in the East Palace is imagined as a dragon stretching from north to south, consisting of 30 stars. Stars are relatively static. When the position of the earth's revolution makes the dragon constellation and the sun in the same direction, the sunlight will drown the starlight, and people will not see the dragon in the sky. After a while, the position of the earth moved and the dragon constellation appeared again. Time and again, the ancients discovered this law and used it to judge the seasons. The first night of the Seven Nights East Palace, known as the "Dragon Horn", appeared on the horizon, which was the time when spring came, so the ancients took its appearance as a sign of the arrival of spring. At this time, it coincides with the rainy solar term in February of the China lunar calendar, resulting in the saying that "on February 2nd, the dragon rises". Bai Juyi, a famous poet in the Tang Dynasty, said in a poem: "On February 2, it was sunny and rainy, and the grass buds were born for a while; The light shirt is thin and the horse is young, and the cross is full of words. " Customs on February 2nd When the Spring Festival comes, in most parts of northern China, every family carries lanterns to fetch water from wells or rivers in the morning. When they get home, they light lanterns, burn incense and offer offerings. In ancient times, people called this ceremony "attracting dragons". On this day, every household will eat noodles, fried oil cakes and popcorn, which are compared with "picking the dragon's head", "eating gentian", "golden beans bloom, the dragon king ascends to heaven, the clouds are raining, and the grains are abundant" to show good luck.
