via Vietnam Net, 02 February 2022: The gold seal of Emperor Minh Mang, one of the national treasures of Vietnam.
In 1945, the Nguyen Dynasty gave King Minh Mang’s priceless golden seal (aka Imperial Seal Ton Than chi bao) to the Government.
The Imperial Seal Ton Than chi bao changed hands after the August Revolution. Hue’s Ngu Phung level, on the Ngo Mon tower platform, was the location of this transfer on August 30, 1945.
Tran Huy Lieu, Nguyen Luong Bang, and Cu Huy Can were among those from the Provisional Revolutionary Government’s envoy who received King Bao Dai’s abdication sword. It was also decided that the dynasty’s property would be turned over.
Treasures, including Imperial Seal Ton than chi bao, were taken to Hanoi after the abdication rites.
