A publication set, titled "Mysterious Hue", consists of three books namely: “Hue, the mystery” (by Louis Chochod), “Gia Long Mausoleum” (by Léopold Cadière), and “The collection of maps and sites in Hue Imperial City” (by Henri Cosserat and Léopold Cadière).

On August 15, at the mausoleum of Emperor Gia Long, the People's Committee of Hue City in collaboration with Hue Monuments Conservation Center held the inauguration of waiting lounges for visitors and water supply stations at three locations, which are the mausoleum of Emperor Gia Long, the mausoleum of Emperor Minh Mang, and the mausoleum of Emperor Dong Khanh.

That is Gia Long Mausoleum (also known as Thien Tho Mausoleum), located in Huong Tho Commune (Hue City), which is around 15km to the Southeast of the city center.

Hai Duong Commune (Hue City) is considered a most arduous and challenging place with a long coastline to the southeast and Tam Giang lagoon to the southwest. Through many generations exploring the land, establishing villages and settling down, the people of Hai Duong have suffered a lot of pressure from waves and winds; nevertheless, they are still living in harmony with the harsh nature and living on marine products.

Inside the Hue Imperial Citadel, Can Chanh – the most important palace after Thai Hoa Palace – was built in the 3rd year of Gia Long’s reign (1804) and destroyed in 1947. This is also the palace that is assessed by Western scholars as the most beautiful and splendid construction of the imperial citadel.

It is the Huong River, the river that "embraces Hue in its heart", which is also a priceless gift that nature has dedicated to this place. The Huong River is magnificent from the upstream, with a peaceful beauty and full of poetry as it confluences and hugs around gardens and villages such as Kim Long, Nguyet Bieu, Vy Da, Gia Hoi, Bao Vinh, and Sinh village, etc. And then, before pouring water into the sea, the downstream river area is a place to make a living, which is hard but close and dear to the locals.

Kham Thien Giam - an institution specialized in observing and studying astronomy, weather forecasting, calendar making, and timekeeping to determine the agricultural seasons for the people, was constructed by the Nguyen dynasty during the reign of Emperor Gia Long.

On April 20, Hoang Tuan Long, an architect from Ho Chi Minh City, confirmed that he would continue to implement the volunteer community project of the work "Map of Vietnam" made from giang toothpicks at the BOARC exhibition – the Exhibition of handmade creative designs, which is due to take place from April 28 to May 5 (within the framework of Hue Traditional Craft Festival 2023).
