3 famous generals of the Hung Due Vuong era
Tri Yeu communal house worships 3 tutelary gods, Chang Rong Dai Vuong, Cao Son Dai Vuong and Quy Minh Dai Vuong. According to legends and genealogy, at Lang Xuong Cave, Gia Hung district, there is a Nguyen family, originally descendant of a tycoon named Cong Linh, whose wife is Cao Thi Nham. One day, Mr. Linh went to Tam Dao mountain to pick medicine, leaning on a stone table to rest for lunch. In his dream, he saw two divine generals, one wearing a tiger's hat, wearing a red brocade robe, riding a pink horse claiming to be Cao Son Than Vuong. One wearing a seven-season hat, wearing a blue brocade robe, riding a white horse, claiming to be Quy Minh Than Vuong.
Soon after, his wife gave birth to 2 handsome, simple, and unusual sons. One person had a red birthmark on his forehead in the shape of a square seal, so he was named Cao Son. The other person had hands longer than his knee, with seven moles on his face, resonating like bells, and moles arranged on both shoulders into the words "Hien Minh", so he was named Quy Minh.
Both grew up quickly and became healthy, eager to hunt and hunt, and diligently practiced martial arts. At the age of 12, his parents passed away, Tan Vien Son Thanh brought the two brothers Cao Son and Quy Minh to live together. In about a few years of purity, the three brothers respected each other like siblings. Tan Vien was given a magic bamboo stick by Thai Bach Tinh Quan, and was given a book of wishes by Long Vuong, capable of dispelling dangers, saving suffering, saving people, and helping people. Saint Tan Vien divided Cao Son and Quy Minh as the left and right shoulder gods, both following the mountainous territory to govern.

When Thuc Phan invaded, King Hung Due Vuong appointed Tan Vien Son Thanh as the Grand Marshal to command the five army lines, appointed Cao Son as Ta do dai Dai phu, and Quy Minh as Huu do dai Dai phu. During the years of peace in the world, the two men went to inspect many places to pacify the people.
When they arrived in Dong Trang region in Tri Yeu, the two men met Chang Rong, the son of Mr. Tran Lan and Mrs. Nguyen Thi Mieu. When he was born, Chang Rong had a face like a dragon's face, eyes as bright as a tiger's eyes, from a young age he had a heroic spirit, ingenuity, and superior strength. Heroic people around the region came to ask to be under his command up to hundreds of people. His gang often went to collect wealthy people's property to help the poor. Knowing Chang Rong's background, Mr. Cao Son and Mr. Quy Minh immediately admitted him and made Chang Rong a deputy general.
Chang Rong returned to Tri Yeu's hometown to recruit troops, build a defense system, and then contributed ideas to help Cao Son and Quy Minh defeat the enemy. Due to their glorious achievements, Cao Son and Quy Minh were appointed by King Hung as Head of the State of Restriction and Left Chancellor of the State of Restriction. Chang Rong was appointed Binh Nhung Hau. Trang Tri Yeu was appointed as the land of Ho nhi, exempted from taxes and labor taxes. Chang Rong spent money to buy more fields and ponds and gardens to divide equally among the people, and taught the people to grow cereals, raise silkworms, and weave silk.
During the Nguyen Dynasty, the king appointed Mr. Cao Son and Quy Minh as Thuong Dang Than and many communes around the area worshiped them. King Khai Dinh in the 9th year (1924), appointed Chang Rong as "Dragon Dragon Than, tôn Than, Thuong Dang Than".
