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.

Throughout the S-shaped strip of the land of Vietnam, Ao dai can be found in every region. Specifically, in Hue, Ao dai has become a part of the cultural identity and unique beauty of the people here. An important milestone in Hue Ao dai costume was in 1744, after Lord Nguyen Phuc Khoat ascended the throne in Phu Xuan, he promulgated many policies and mentioned the modification of costumes. Thereafter, during the Nguyen Dynasty, the court issued an order, creating an opportunity for Hue women in particular and Vietnamese women in general to wear Ao dai regularly. Accordingly, the tradition of wearing Ao dai gradually entered the daily life of people.

The artifacts selected for identification are representative items typical of the Nguyen Dynasty's royalty and officials, such as the golden throne, palanquins, ceremonial shoes (things used in daily life and rituals), gold and jade branches (interior decorations), and the Xam Huong set (a recreational activity).
