February 2nd is not a solar term, but a traditional folk festival. February 2 generally refers to the dragon raising its head, also known as "Spring Farming Festival", "Farming Festival" and "Spring Dragon Festival". Dragon heads up every year on the second day of the second lunar month, commonly known as Qinglong Festival. Legend has it that this is the day when dragons look up. It is a traditional festival in urban and rural areas of China. Celebrate the "Dragon Head Festival" to show respect for the dragon and pray for rain so that God can help ensure a bumper harvest. Because "the dragon looks up" means ending hibernation, reviving everything, holding one's head high and holding one's head high, people have also regarded February 2 as a day to bid farewell to the old and welcome the new and turn to good luck since ancient times.

February 2nd is also said to be the birthday of the land father-in-law, which is called "land birthday". In order to "warm the life" of the land god, some places have the custom of holding "land meetings": every family raises funds to celebrate the birthday of the land god, burns incense and sacrifices at the land temple, and sets off firecrackers with gongs and drums. There is also a saying that "the dragon looks up in February and the dragon ends in August" in the Zhuang area in central and northern Guangxi.

As the saying goes: "On February 2nd, the dragon looked up and everyone became a farmer." At this time, the sun's spirit rises, the earth thaws, and spring ploughing will begin. This is the time to transport manure and plow the fields.

Extended data:

In ancient astronomy in China, the ecliptic was identified as 28 constellations on Sunday, which were called "Twenty-eight Nights". The ancients divided the 28 stars into four palaces according to the southeast and northwest, with 7 nights in each palace, and described the four palaces as four kinds of beasts according to their images: "Qinglong, White Tiger, Suzaku and Xuanwu". The "dragon" mentioned when the dragon looked up on February 2 refers to the seven nights of Oriental Qinglong.

The rise of the dragon is a reflection of the festival in China's ancient farming culture, and its origin is related to the understanding of star movement and agricultural solar terms in ancient astronomy. According to historical records, since the Tang Dynasty, China people have the custom of raising their heads on February 2nd. People in the Tang Dynasty have regarded the second day of February as a special day, saying that it is a day to welcome wealth, and eating "fruit to welcome wealth" on this day means eating some snacks.
