The Jade Emperor belief and custom in Xiangyun Temple of Hushan is a folk culture phenomenon with a wide range of influence, and has outstanding characteristics of folk religious belief. As Xiangyun Temple has a long history and rich historical and cultural accumulation, it is the main place for Jade Emperor cultural activities and plays an important role in promoting the research, exchange and development of Jade Emperor culture. Its God Birthday Sacrifice, especially the "Sand Flower Technique", originated from the local sand casting technology. It uses the principle of sparks splashing in cast iron to artificially create the artistic effect of fireworks. It is the oldest kind of fireworks in my country. This is a form of folk activity display that "entertains gods" and "entertains people", and retains the original traditional handmade folk art creation. In January 2009, "Xindu Xiangyun Temple Jade Emperor Belief Customs" was announced by Putian Municipal People's Government as the second batch of Putian City's intangible cultural heritage list. Jade Emperor belief is a major component of Taoist culture, which originated from the ancient worship of the Emperor of Heaven. During the Shang Dynasty, people called the highest god the Emperor, or God. After the Western Zhou Dynasty, the title of God has developed greatly, including Huangtian, Shangtian, Tiandi, Huangtian Shangdi, Haotian Shangdi and many other titles. The Book of Songs Zhou Song Shimai states: "Shimai's country, Haozi's son, in fact, the right order has Zhou". The monarch claimed that he was the son of the Emperor of Heaven and called himself "Son of Heaven". The Son of Heaven was the legitimate representative of the human world to communicate with the Emperor of Heaven. The Analects of Confucius Yao said: "If you don't know your destiny, you can't be a gentleman." The people should follow the benevolent and noble people who know their destiny, advocate the theory of destiny, and implement the wise politics of benevolent monarchs. Confucianism has been preaching for more than 2,500 years and still has a certain influence today. During the Eastern Han Dynasty, Taoism emerged, so the Emperor of Heaven became the emperor of the world of gods and immortals, and was in charge of the three realms, ten directions, four lives, and six ways. The titles of Jade Emperor, Jade Emperor, Jade Emperor, Haotian Jinque Jade Emperor and other gods were derived from this, and the Jade Emperor also became the highest god worshipped by the people (mainly the Han nationality). By the Tang Dynasty, the belief in the Jade Emperor had already taken shape and gradually became a revered god in Taoism. The birthday of the Jade Emperor was set as the ninth day of the first lunar month, which is the so-called "Jade Emperor's Birthday". Wang Kui of the Ming Dynasty said: "The birth of gods is based on righteousness. The Jade Emperor was born on the ninth day of the first lunar month, and the yang number starts from one and ends at nine." ("Li Hai Ji") The number "nine" was often an imaginary number representing a large number or majority in ancient times, and was also used as an extreme number or the largest number. "Su Wen San Bu Jiu Hou Lun" said that "nine" is "the ultimate number of heaven and earth, starting from one and ending at nine", so the sky is high and called "nine layers", the earth is deep and called "nine springs", the territory is wide and called "nine domains", the immortals are called "nine immortals", the deepest earth is called "nine hells", and the deepest water is called "nine abysses". "Nine" is a mysterious and sacred number, so the ninth day of the first lunar month, which is the most honorable day, can only be occupied by the Jade Emperor. The belief in the Jade Emperor is one of the main folk beliefs in Putian. There are more than 80 temples dedicated to the Jade Emperor in the city, which is one of the most widespread and common areas in Fujian Province and even in the whole country. The belief in the Jade Emperor in Hushan Xiangyun Temple has a long history and rich connotations. Its temple fair activities are regularly held on the ninth day of the first lunar month, the birthday of the Jade Emperor, with grand birthday celebrations and sacrificial ceremonies such as chanting scriptures and repentance, in order to pray for peace and prosperity, good weather, and good luck. Believers come from all over Putian. At the same time, there are also famous pilgrimage groups from Taiwan, overseas Chinese and Chinese from Singapore, Australia and other countries, as well as pilgrims from inside and outside the province. It is one of the most influential birthplaces of the belief in the Jade Emperor in Fujian and Taiwan. The carrier of the belief in the Jade Emperor in Xiangyun Temple, Hushan Xiangyun Temple, was first built during the Guanghua period of Emperor Zhaozong of the Tang Dynasty (898), and has a long history of 1112 years. Emperor Daojun of Song, i.e. Emperor Huizong, rebuilt the palace in the first year of Daguan (1107), covering an area of 100 mu, with a magnificent scale and prosperous incense. It was expanded in the Ming Dynasty, among which "Hushan Academy" was built by Lin Junxing, the Minister of the Ministry of Punishment of the Ming Dynasty. It is a Xieshan roof-sucking and through-beam structure, retaining the architectural style of the Ming and Qing Dynasties. There are 5 Song Dynasty stone carvings and 13 Ming and Qing Dynasty cultural relics in the palace, which are important physical materials for studying the Jade Emperor culture. Hushan Xiangyun Hall is the venue of Putian Jade Emperor Culture Association, Jade Emperor Culture Research Association and the location of Putian Hushan Academy, a municipal cultural relic protection unit. It has successfully hosted the Fujian-Taiwan Folk Customs and Tourism Academic Seminar for many times, and actively carried out Fujian-Taiwan and foreign Jade Emperor culture and folk folk culture exchanges. In recent years, it has received as many as 6 batches of teams led by Li Bingnan, President of Taiwan Jade Emperor Culture, and also conducted folk cultural exchanges with experts from more than 10 countries including the United States, Britain, France, Germany, Switzerland, Italy, and Malaysia. It is an important base for Fujian-Taiwan Jade Emperor beliefs and foreign folk cultural exchanges. The belief and customs of Hushan Xiangyun Temple are closely related to the development of Jade Emperor culture in Putian. The temple fair activities are rich in content, especially the "Sand Flower Art", which is a handmade folk art creation with regional characteristics. It has been developed for more than 400 years and passed down from generation to generation. "Sand Flower Art" is a handmade folk art creation rooted in the folks and developed among the folks. It expresses the traditional concept, simple psychology and good wishes of the majority of believers to pray for the blessing of "God", to receive blessings and auspiciousness, and to protect the peace of the country. It is not only a form of folk activity of "entertaining gods", but also a social and cultural activity content of "entertaining people". From this, we can get a glimpse of the influence of Jade Emperor belief in the process of activities, as well as the inherent relationship and profound connotation of this activity and Jade Emperor belief. In the Hushan Xiangyun Temple Jade Emperor Belief Customs Temple Fair, in addition to various sacrificial utensils, Taoist altar utensils, and folk art performance props, the main related utensils and products of its "Sand Flower Art" are: 1. Utensils: a monkey stove with a height of 1.5m and an inner tube of 28cm, made of refractory paste; a hand-pulled wooden blower; ten pieces of 1m long and 5cm diameter bamboo pieces (bamboo) for frying flowers, made into spoons; ten 50cm wooden frying flower hammers. 2. Raw materials: One hour of sand flower spraying requires: 150 kg of sand (pig iron); about 80 kg of charcoal or coke. 20 kg of limestone. 3. Select 5 lychee or longan trees with thick circumference, lush leaves, and tall. After the sand is smelted into molten iron, it is poured on the branches and leaves of the trees, colliding with each other, and countless incandescent flowers fly, forming a spectacular scene of "fire trees and silver flowers all night long". The sand flower technique of Jindun Village in Xindu is an original handmade folk art creation rooted in and developed among the people. Its unique traditional technique style and regional cultural characteristics involve many fields such as history, society, agriculture, plants, casting technology, folk art, and folklore. It has five major characteristics of rarity, inheritance, scientificity, mass participation, and ornamentalness, as well as important values in humanity, art, research, and social impact.
