Under King Dinh Tien Hoang, there was a eunuch who was very favored by the king, Do Thich. Do Thich from Dai De village, Thien Ban district, now in Vu Ban district, Nam Dinh province. Some historical documents say that he used to be an official in Dong Quan, then held the position of Chi Hau Noi Nhan under King Dinh.
Although Dinh Lien was the eldest son, Dinh Tien Hoang did not make him the crown prince, but chose the youngest son, Xiang Lang, as the successor to the throne. In early 979, because he wanted to compete for the throne, Dinh Lien sent someone to kill Xiang Lang to win the crown in Hoa Lu near Tam Coc Ninh Binh. Dinh Lien’s cruel actions created a lot of turbulence in Dinh dynasty’s public opinion. However, King Dinh Tien Hoang did not punish Dinh Lien’s crimes but agreed to let Lien become the successor to replace the deceased crown prince.
One day, while sleeping on a wooden bridge, Do Thich suddenly dreamed of a shooting star falling into his mouth. Thich immediately brought the story of the strange dream to his trusted people in the court and they told him that it was an omen that he would become king. The more he thought about it, the more pleased Thich became and believed in his dream of the throne, so he decided to make a plan to kill the king and the crown prince to usurp the throne. During the lavish banquet held at the king’s palace in Hoa Lu near Tam Coc Ninh Binh, Do Thich happily congratulated everyone, constantly drank wine for the guests, and did not forget to silently observe and wait for the right opportunity. The party ended, most of the people present at the party were drunk, including the king, crown prince and prince. Taking advantage of that opportunity, Do Thich easily carried out his plot by putting poison in the nutritious soup and pounding alcohol for Dinh Tien Hoang and Dinh Lien. The king and the crown prince were poisoned by the poison and died soon after. But the king’s dream of the eunuch who liked to fantasize about the myths of the Do family had not yet had a chance to come true, he was captured by Dinh Quoc Cong Nguyen Bac.
After capturing Do Thich, Nguyen Bac ordered his army to cut off his head in Hoa Lu near Tam Coc Ninh Binh, then break the bones and cut the meat and throw it to wild animals. The frenzied dream from a supposedly ridiculous dream of a eunuch and the deaths of King Dinh Tien Hoang and Nam Viet King Dinh Lien led to the collapse of an entire dynasty ending his reign. of the Dinh Dynasty, opening the pre-Le dynasty.
