龙抬头，又称春耕节、农事节、青龙节、春龙节等，是中国传统节日，时间为农历二月初二。龙抬头源于自然天象崇拜，与古代天文学对星辰运行的认识和农耕文化有关。二月初二时节，"龙角星"（即角宿一星和角宿二星）会从东方地平线上升起，民间认为这是"龙抬头"的标志，故称"二月二，龙抬头"。龙在中国传统文化中是祥瑞之物，主管云雨，农历二月初二正值"惊蛰"前后，万物复苏，春雨增多，正是春耕播种的重要时节。龙抬头寄托了人们祈龙赐福、风调雨顺、五谷丰登的美好愿望。这一天，各地有丰富多彩的民俗活动，如剃龙头、吃龙食、祭龙王、舞龙灯等，充满了浓厚的文化气息和生活情趣。

龙抬头节的起源与古代天文学和农耕文明密切相关。在中国古代天文学中，古人选择黄道赤道附近的二十八组星宿作为坐标，称为"二十八宿"，并按东西南北四个方位分为四组，产生"四象"：东方青龙、西方白虎、南方朱雀、北方玄武。其中，东方七宿：角、亢、氐、房、心、尾、箕组成一个完整的龙形星象，称为"苍龙七宿"。每年农历二月初二晚上，苍龙七宿中的"龙角星"（角宿）开始从东方地平线上升起，接着"龙头"（房宿、心宿）、"龙身"、"龙尾"（尾宿、箕宿）也逐渐显现，就像一条巨龙昂首升天，故称"龙抬头"。这一天象恰逢春回大地、雨水增多的时节，古人认为龙掌管降雨，龙抬头意味着雨水将至，适宜春耕播种。因此，二月二逐渐演变成一个重要的传统节日。关于龙抬头的传说也很多，其中最广为流传的是唐朝武则天称帝的故事。传说武则天废唐立周为帝，惹怒了玉皇大帝，玉帝传令三年内不许向人间降雨。司掌天河的龙王不忍百姓受苦，偷偷降了一场大雨。玉帝得知后大怒，将龙王打下人间，压在大山之下，并立碑："龙王降雨犯天规，当受人间千秋罪。要想重登灵霄阁，除非金豆开花时。"人们为了拯救龙王，到处寻找开花的金豆。到了农历二月初二这天,人们翻晒玉米种子时，突然想到，玉米就像金豆，炒开了花不就是"金豆开花"吗？于是家家户户爆玉米花，在院子里设案焚香，供奉"开花的金豆"。龙王抬头一看，知道百姓在救它，便大喊："玉帝，金豆开花了，放我出去！"玉帝一看金豆真的开花了，只好传令将龙王释放，继续为民间降雨。从此，民间形成了二月二吃爆米花、炒黄豆的习俗。

The Dragon Head-Raising Festival, also known as the Spring Ploughing Festival, Agricultural Festival, Azure Dragon Festival, or Spring Dragon Festival, is a traditional Chinese festival celebrated on the second day of the second lunar month. It originates from ancient worship of natural astronomical phenomena and is related to ancient astronomy's understanding of celestial movements and agricultural culture. Around the second day of the second month, the 'Dragon Horn Stars' (Jiao Su 1 and Jiao Su 2) rise from the eastern horizon. Folklore believes this is the sign of 'the dragon raising its head,' hence the saying 'On the second day of the second month, the dragon raises its head.' In traditional Chinese culture, the dragon is an auspicious creature that controls clouds and rain. The second day of the second lunar month coincides with the 'Awakening of Insects' solar term, when all things come back to life and spring rains increase - it is a crucial time for spring plowing and sowing. The Dragon Head-Raising Festival embodies people's wishes for the dragon's blessings, favorable weather, and bountiful harvests. On this day, various colorful folk activities take place across regions, such as getting dragon head haircuts, eating dragon foods, worshipping the Dragon King, and performing dragon dances, filled with rich cultural atmosphere and life interest.

The Dragon Head-Raising Festival's origin is closely related to ancient astronomy and agricultural civilization. In ancient Chinese astronomy, ancient people selected twenty-eight groups of constellations near the ecliptic and celestial equator as coordinates, called the 'Twenty-Eight Mansions,' and divided them into four groups according to the four directions of east, west, south, and north, producing the 'Four Symbols': Azure Dragon in the east, White Tiger in the west, Vermilion Bird in the south, and Black Tortoise in the north. Among them, the eastern seven mansions - Jiao, Kang, Di, Fang, Xin, Wei, and Ji - form a complete dragon-shaped constellation called the 'Azure Dragon Seven Mansions.' Every year on the evening of the second day of the second lunar month, the 'Dragon Horn Star' (Jiao Su) in the Azure Dragon Seven Mansions begins to rise from the eastern horizon, followed by the 'dragon head' (Fang Su, Xin Su), 'dragon body,' and 'dragon tail' (Wei Su, Ji Su) gradually appearing, like a giant dragon raising its head to the sky, hence called 'dragon raising its head.' This celestial phenomenon coincides with the season when spring returns to earth and rainfall increases. Ancient people believed dragons controlled rain, and the dragon raising its head meant rain was coming, suitable for spring plowing and sowing. Therefore, the second day of the second month gradually evolved into an important traditional festival. There are also many legends about the Dragon Head-Raising Festival, the most widely circulated being the story of Empress Wu Zetian of the Tang Dynasty. Legend has it that Wu Zetian's abolition of the Tang Dynasty and establishment of the Zhou Dynasty angered the Jade Emperor, who ordered no rain in the mortal world for three years. The Dragon King in charge of the Heavenly River couldn't bear to see people suffer and secretly sent a heavy rain. The Jade Emperor was furious upon learning this, cast the Dragon King down to the mortal world, pressed him under a mountain, and erected a monument: 'The Dragon King violated heavenly rules by bringing rain and should suffer punishment in the mortal world for a thousand autumns. To return to the Heavenly Palace, only when golden beans blossom.' People searched everywhere for golden beans to save the Dragon King. On the second day of the second lunar month, when people were drying corn seeds, they suddenly realized that corn was like golden beans, and wouldn't fried corn be 'golden beans blossoming'? So every household popped corn and set up altars in courtyards to burn incense and offer 'blossoming golden beans.' The Dragon King looked up, knew people were saving him, and shouted: 'Jade Emperor, golden beans have blossomed, let me out!' The Jade Emperor saw the golden beans had indeed blossomed and had to order the Dragon King's release to continue bringing rain to the mortal world. Since then, the folk custom of eating popcorn and roasted soybeans on the second day of the second month was formed.
