History books of Nguyen Dynasty record that after ascending the throne in 1802, Emperor Gia Long established the medicine agency to serve the court. However, it was not until the reign of Emperor Minh Mang that the structure of Thai Y Vien (Imperial Medicine Institute) was gradually completed. From then on, the recruitment of personnel to Thai Y Vien was extremely tight and serious.

After two archaeological excavations of the National Relic of Mount Ban (An Tay Ward, Hue City), experts have discovered a number of vestiges and relics that contribute to confirming that this place is where Nguyen Hue set up Nam Giao Esplanade to sacrifice to “heaven and earth” before ascending the throne. Also, according to the latest archaeological information, experts recommend turning this relic into a special national relic.

The area of Thua Thien Hue passing through Huong Tra is truly a sequence of magical sites of heaven and earth. From low to high, the land starts from the sea, where the waves rumble, to the vast lagoon with the silver moon shining on the water, to the fertile plains of corn and rice, to the green midland at the foot of the mountain and the lush green hills ascending to high mountain peaks.
