Tô-định, governor of Giao-chì (of Annam), had infuriated the people with his despotic administration. The killing of Thi-sách, husband of Trung-trắc, whom he had executed, caused an explosion of popular hatred and anger against him. Trung-trác, assisted by her sister, put herself at the head of the oppressed population which revolted. The first thing they did was take and behead the odious governor.
The enterprise was crowned with complete success. Trưngtrác marched against the Chinese and dispersed them. Its authority was so great that from the province of Lánh-nam, more than 65 cities submitted to it. She ruled the country for three years and wisely.
However, China (Dông-hán) sent Má-viện to reconquer the country.
The successes were roughly divided in the various battles that first took place. But in the end, Má-viện was definitely victorious.
The two sisters Trung-trác and Trung-nhị were killed on the battlefield.
To perpetuate the memory of these two heroines and preserve the memory of their bravery, a temple was dedicated to them, all the ornaments of which were black; the color red (color of blood) was prohibited there.
Má-viện, victor, had a bronze column erected in remembrance of his triumph, and to serve for the delimitation of the border, at Cô-lâu, in the country called Klâm-châu, with this inscription: Đồng-trụ-thiết -giao
chi-diệt, the bronze column demolished (fallen), the race of Giao-chi abolished. It is for this reason that the inhabitants of Annam, fearing that the column would fall and that it was made of the Annamite nation, threw there, each in passing, pieces of stones, broken pots, etc. to consolidate the column. Over time, the column disappeared, probably buried by the various debris that had been thrown into it.
