As a ritual rooted in ancient Chinese agricultural civilization and having a profound impact on the East Asian Han cultural sphere, the Ji Tian ritual originated from the cosmology of "the emperor personally cultivates" during the Shang and Zhou dynasties, carrying the political ideology of "respecting heaven and protecting the people". Today's New Year's Land Ceremony in Vietnam has been included in the Vietnamese National Intangible Cultural Heritage List and is held on the seventh day of the first lunar month every year. The Jitian ritual originated in China and has lasted for nearly a thousand years in Vietnam, undergoing dynastic changes and social transformations, gradually forming local characteristics. In the history of both China and Vietnam, there has been a tradition of "agriculture oriented" farming: the "Ji Tian Li" ceremony, as a folk New Year festival custom, embodies the Vietnamese people's simple expectations for good weather and abundant crops. Ji Tian means the land personally cultivated by the emperor. The Ji Tian Li is a ceremony held by emperors before spring plowing to personally cultivate farmland, aiming to set an example and encourage agricultural labor. Vietnam has been founded on agriculture since ancient times, and its rice cultivation culture has a long history. Geographically, the Changshan Mountains in the central region are like carrying poles carrying the two major "valley baskets" of the Red River Plain and the Mekong River Plain. The Red River Plain is formed by the alluvial deposits of the Red River and its tributaries, with flat terrain and fertile land; The Mekong Plain has a low and flat terrain with a dense water network, making it very suitable for agricultural production. In addition, most regions in Vietnam often have a tropical monsoon climate, which is humid and rainy throughout the year. The rice in the southern region can reach three harvests per year. The Ji Tian ritual and its implications of encouraging agriculture, praying for good years, and remembering the source of water are particularly important for a traditional agricultural country like Vietnam. Ji Tian has been recorded in Chinese culture for a long time. In the Book of Songs, Zhou Song, and Zai Yi, it is written: 'Yi Xi Cheng Wang, who was once a false ruler, led the farmers and sowed a hundred grains.'. In the preface to the poem, it is said that 'spring leaves the fields and prays for the country's prosperity'. It is known that the Ji Tian ritual is held to worship the ancestral temple, pray for the country, and encourage farmers to cultivate. Ji Tian is also known as Ji Tian, Ji Tong Ji, and Ji Yi. According to the Spring and Autumn Annals, it is said that "farming comes after the suburbs". Therefore, Ji Tian is called Emperor Ji because he achieved great success through manual labor. Rulers borrow the power of the people to cultivate public fields, so the fields personally cultivated by emperors are also known as registered fields. Jitian may also have originated from the primitive society's "public fields", where clan leaders withdrew from labor due to changes in status and only symbolically worked underground during the beginning of spring. After the formation of the monarch's power, it gradually evolved into the ritual of the emperor's land registration. During the Zhou Dynasty, the Ji Tian ritual was already quite complete. The "Guoyu · Zhouyu" records in detail the grand occasion of the Zhou emperor's registration in the fields: "Ji Ji, the Later Ji Supervisor, the Shanfu and Nongzheng Chen Jili, the Grand Historian praised the king, and the king respectfully obeyed. The king cultivated one grain, three classes, and finally a thousand acres of land for the common people..." The prince personally led his courtiers and farmers to cultivate the fields, setting an example to persuade the farmers to cultivate mulberry trees. After the Zhou Dynasty, rulers of various dynasties followed this system and continuously enriched the ritual content, such as adding poetry, elegant music, and dance, making it one of the important court spring festival ceremonies. In the 15th century, Wu Shilian compiled the "Complete Records of the Grand Historian of Vietnam - Hongpang Ji", which stated that the founder of Vietnam, King Xiong, was the third generation descendant of the Shennong family. Therefore, before the Vietnamese people held the land registration ceremony, they also had the habit of bathing and burning incense to worship Shennong. Legend has it that King Xiong, as the tribal leader, taught his tribe and descendants how to plant rice. In order to express gratitude to King Xiong, a festival event was often held in Mingnong Fang, Echizen City, Fushou Province, where King Xiong taught rice cultivation. According to historical records such as the Complete Records of the Grand Historian of Vietnam and the Brief History of Vietnam, on the seventh day of the first lunar month in the spring of 987 AD (Dinghai year), Li Huan personally went to the fields near the capital to cultivate, setting a precedent for Vietnamese land rituals. The Complete Records of the Grand Historian of Vietnam "records:" In the spring of the fourth year of Yongxi in the Song Dynasty, in the eighth year of Dinghai, the emperor first cultivated his land in Duishan and obtained a small urn of gold. He also cultivated Panhai Mountain and obtained a small urn of silver, hence the name Jin Yin Tian. "This type of content also appears in the" Brief History of Vietnam ": Also held at Team Mountain. This legendary record indicates that Le Huan wanted to use it to express the meaning of the country's "gold and silver surplus warehouse", and also reflects the good intentions of Vietnamese rulers to encourage agriculture. Since the establishment of the Ji Tian ritual by Li Huan, although the degree of emphasis on this agricultural auspicious ritual has varied among different dynasties, it has been consistently upheld as a whole. During the Li Dynasty, with the strengthening of national strength, Li Gongyun established the capital in Shenglong (now Hanoi), and the Rites of Rites of Rites became a more grand and formal court ceremony. Li Taizong once performed the ritual of cultivating land twice, saying, 'If I do not cultivate diligently, I will not be able to provide abundant rice and lead the world.' He was praised by the historical officials at that time. In addition to personally cultivating the land, the emperor also drove to watch farmers harvest rice. In the Chen Dynasty, due to continuous wars, when the emperor was unable to cultivate crops himself, he sent officials to build altars to worship the country. Due to the distance between the land personally cultivated by the emperor during the Li Chen period and the capital city of Vietnam at that time, Shenglong City, the rulers of the Later Li Dynasty re chose fertile land near the capital city as their land, in order to facilitate the emperor's annual spring cultivation and improve the regulations of land cultivation etiquette. In the Nguyen Dynasty, Emperor Mingming perfected and standardized this ritual, and formulated it into a law. He issued an edict stating that "performing the ritual of land registration is the emperor's duty," and as a result, Emperor Mingming was known as the "Emperor of Farmers. The "Qinding Danan Huidian Case" compiled during the Nguyen Dynasty recorded the complete process of the ceremony of cultivating land: "In the fifth year of Chengtai, an edict was issued stating that farmers are the foundation of the world. Since ancient times, they have devoted themselves to cultivating imperial land and devoutly serving the people, setting an example for the people. The ceremony is the most solemn." The emperor held the plowing ceremony with the plow on his right and the whip on his left, playing elegant music and singing with ease. The prince, meritorious officials, civil and military officials, and elderly farmers are second to none in the fields. After the ceremony, the emperor held a banquet to reward the farmers, and the high-quality rice produced in the fields during autumn was used for worship and sacrifice the following year. From a historical perspective, the Jitian ceremony is one of the most important royal ceremonies of spring and also the most significant agricultural ceremony. In 2009, the Henan Provincial Government of Vietnam and the Vietnam Academy of Arts and Culture jointly proposed the initiative to restore the citizenship ceremony, with the starting point of promoting agricultural development; Protecting the intangible cultural heritage of the Red River Delta; Promote local socio-economic development. The revival of Jitian Li has received response from the Vietnamese people and government support. In the revival ceremony, elderly people from local villages were selected as representatives of the image of Emperor Li Daxing, dressed in dragon robes and masks, and performed scenes of the emperor personally farming. At the same time, the restoration of the Jitian ritual is combined with the local customs of Duishan Village, and the New Year festival custom of Vietnamese people praying for blessings and disaster relief gives more vitality to the royal ceremony. During the first month of the new year, when all things are reborn, people offer sacrifices to various natural deities such as the City God, the Divine Farmer, the Cloud God, the Rain God, the Thunder God, and the Electric God, in order to pray for good weather, abundant crops, prosperous population, and national prosperity. During this time, people also hold activities such as chess, drawing water buffalo, cockfighting, and wrestling, adding "entertaining" elements and corresponding folk meanings to the Jitian ritual. Although Hue, Bac Ninh, Phu Tho provinces and other places in Vietnam have a tradition of holding the Ji Tien ceremony, the Tuan Shan Society in Henan Province is the first recorded place in Vietnam to hold the Ji Tien ceremony, making it the largest scale of Ji Tien ceremony held there. As a cultural heritage, Jitian Li has been deeply excavated and developed into an annual regional cultural landmark, driving local festival tourism and handicraft revival. The revival of Ji Tian Li is not only a restoration of an ancient festival, but also a tribute and inheritance of the agricultural values of valuing, encouraging, and assisting agriculture. More broadly speaking, the concept of respecting nature, fearing heaven and earth, and thinking about the origin runs through the Jitian ritual, reflecting the Eastern wisdom of harmonious coexistence between humans and nature. Agriculture is the backbone of Vietnam's economy, and contemporary farming practices have reshaped the country's image of prosperity, peace, and people's well-being, while also promoting the development of agriculture and rural areas. Both China and Vietnam belong to the agricultural civilization and share a common vision for achieving rural revitalization and green agricultural development. It can be said that the revival of the Jitian ritual has not only aroused people's sense of identity with traditional agricultural culture, but also aligned with contemporary society's concern for agricultural ecology and food security. This traditional festival, which embodies the spirit of thousands of years of rice culture and new ideas of the times, is giving new vitality, continuing to nourish Vietnam's local culture, and adding a precious historical memory to the construction of a shared future between China and Vietnam.
