1. Objects of worship at the communal house
According to sources still kept at Cấn Giang Communal House, such as royal edicts of investiture, deity records, village conventions, etc., Cấn Giang Communal House worships the water deity “Long Vương Hà Bá tôn thần.” This is consistent with the residential area of the people of Cây Chay Village, since the belief in worshipping Hà Bá is one of the beliefs of people living along rivers.
Regarding the origin of the belief in worshipping Hà Bá, some studies hold that this belief was originally a product of residents living in the Yellow River basin in China. Hà Bá was originally fish-bodied and later turned into human form. According to Bác vật chí volume 7, it says: In ancient times, when King Yu observed the Yellow River, he saw a fish-bodied person who said: I am the spirit of the Yellow River, that is, Hà Bá. Originally he was Phùng Di, a person from Đông Hương in Hoa Âm, who attained the Way and transformed into Hà Bá. Hà Bá is the lord of the rivers, calls himself king, has attendants, and organizes an underwater court. People created images of Hà Bá, knelt and prayed to him; during droughts they often burned mountains to pray for rain. Legend has it that the mountain god married Hà Bá’s daughter, so when Hà Bá saw fire he called down rain to save her. Accordingly, in Han culture, Hà Bá, like other water deities, was created as the deity governing the waters of rivers and streams.
In the book Vietnamese Spirituality by Nguyễn Duy Hinh, it is said: in history the Chinese people had the custom of praying for rain, usually to the Dragon King. When the Buddhist idea of the Dragon King was introduced into China, the Dragon King appeared not only with the title of king but also with a human-like appearance, and: although rain is mentioned, the spirituality of Water is mainly the Water Official, the water deity, that is, China’s Hà Bá, which then merged with the Buddhist Dragon King. Hà Bá, like other water deities, is a Water Official, that is, one who governs the waters of rivers and streams, mainly the Yellow River.
Thus, when Buddhism was introduced into Chinese culture, the image of Long Vương Hà Bá showed a fusion with the image of the Four Seas Dragon Kings; Hà Bá had originally been created by the people to perform the function of governing underwater. In the past, the Chinese feudal authorities imposed domination and carried out a policy of cultural assimilation in Vietnam. However, because of similarities in concepts and in the desire for protection and shelter by supernatural forces to conquer the river and sea environment among the people of the two countries, the belief in worshipping water deities in general and the belief in worshipping Hà Bá in particular was quickly adopted by the Vietnamese people and became an indispensable deity in their spiritual life.
Author Tiêu Hà Minh in Tracing the Origins of Idioms wrote: One day, a demon came down from heaven and saw that the Earth God governed a vast area, while Hà Bá governed only a small body of water running around it, so it conceived the idea of seizing part of the river and part of the land here. It immediately went to see the Earth God and asked him for permission to build a citadel, and was agreed to. But before building, it did not perform a thank-offering ceremony, which made Hà Bá furious. Hà Bá then let water flow into the land along underground channels. Wherever the demon’s citadel was built, water eroded it, so the citadel collapsed there. The Earth God saw that the water was encroaching on the great domain under his governance and was angry; he sent his servants to block the water with earth wherever they saw it, not allowing it to spread. At this time, in the underwater palace, Hà Bá saw that his water source was blocked and was annoyed; he raised the water high and beat against the land, causing the land to crumble and drift into the water. The two deities fought, causing landslides, scattered trees, muddy river water, and exhausted people. In the end, both realized that the demon had caused the mischief and decided to meet and negotiate. Hà Bá said: “I am the River God, I govern the river; whoever encroaches on my river, I will punish.” The Earth God also said: “I am the Earth God; whoever encroaches on my land will not get away with it. You and I have nothing to do with each other; let us fight no more, causing landslides, withering trees, and floods that swamp houses.” Then both deities said together: “The land has the Earth God, the river has Hà Bá”… From this story, the idiom “the land has the Earth God, the river has Hà Bá” was passed down orally among the people, containing the conception of the spiritual world in the community culture of the Vietnamese people from the past to the present, with deep educational meaning about the tradition of worship and remembrance of the deities. Over time, no one knows since when, folk people have not been very favorable toward Hà Bá and regard him as an evil deity. Perhaps it began from cases of people drowning, so in folk consciousness they believed they were taken away by Hà Bá. Even so, people still built shrines to worship him in order to express their sincerity to this deity, hoping that he would understand this and not “bring disaster.” As a country with many canals, rivers, and a coastline stretching from north to south, the presence of Hà Bá in the spiritual life of Vietnamese people is not strange. Perhaps knowing that there is a deity governing rivers and waters, in some regions, whenever a funeral procession crosses a bridge, the family often throws small change or votive money down with the intention of paying the ferry fee across the river for the deceased, just as living people must pay road and ferry fees when crossing bridges and rivers to those guarding the ferry landings.
According to historical records, the entries in Khâm định Đại Nam hội điển sự lệ clearly record the approval of establishing shrines and offerings for sacrificing to Hà Bá under the reigns of King Gia Long and Minh Mạng as follows:“In the 14th year of Gia Long, according to a petition approved for Quảng Đức garrison to build a Hà Bá shrine at Thuận Trực estuary in Hà Trung Commune, annually in the second month of mid-spring and the second month of mid-autumn, one day after the sacrifice at Hội đồng shrine, the sacrifice is performed; the offerings are 1 pig and 1 tray of glutinous rice, and an official from Quảng Đức garrison is sent by imperial order to perform the sacrifice. It was also approved to provide 2 people whose names are in the commune register to serve. In the 9th year of Minh Mạng, a proposal was approved: At the place where the Lô River and Thảo River meet in Sơn Tây Trấn, choose a site to build a Hà Bá shrine; annually in spring and autumn sacrifices are held; the offerings are 1 buffalo, 1 pig, 1 tray of glutinous rice, and 2 trays of fruits, and officials of that trấn, wearing hats and court robes, usually perform the ceremony. Every year after the Frost Descent solar term, all rejoice at being safe from waves, and there will be a separate order to distribute incense and silk from the store for a thanksgiving ceremony, with offerings the same as for the spring and autumn sacrifices”. And the granting of edicts of investiture and promotion in rank to Hà Bá: In the first year of Minh Mạng… It was also ordered and approved that: The deity at Thuận An estuary is ranked upper; the deity at Tư Hiền estuary and the Hà Bá deity are all ranked middle; each is granted one edict of investiture; the Hà Bá shrine at Thuận Trực estuary is granted one edict of investiture
Thus, Hà Bá is a deity specializing in governing river and water areas who appears in folk belief. The water deity Hà Bá is not widely worshipped but is worshipped only by people along rivers to pray that everyone will not meet with disaster on the river and to pray that everyone will catch manyfishduring the seasonrain.
In Hà Nội there are a number of relics worshipping Hà Bá such as: Trung Lập Communal House, Hà Bá Temple, Liễu Nội Communal House… At Cấn Giang Communal House there is still one edict of investiture granted to Hà Bá in the 9th year of Khải Định (1924) as follows: “Edict: Sơn Tây Province, Quốc Oai Prefecture, Cấn Xá Commune, Thủy Cư Village worships the Great Sea Dragon King Hà Bá, the water deity, a venerable deity who protects the country and assists the people”. This is historical evidence recognizing the lawful worship of this deity in the past. From this, it helps us better understand the belief in worshipping this deity and the changes in the way this belief has been received in the cultural life of people today.
