Tam Giang - Cau Hai lagoon system is a world-class brackish water area. It is the largest in Southeast Asia, with special value in biological resources and countless gripping things in history and culture.... This area is seen as a "precious biological gem" that nature has bestowed on the ancient capital. With what existent, is it necessary to build an exhibition space or a museum for the Tam Giang - Cau Hai lagoon system?

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.

Hue has come into summer with the peach of the sun and the sound of cicadas resounding on the canopy of leaves. Sometimes the spring still pours mist into the early sunrise and late sunset. With the desire to see ‘the region of weeping willow’ and the ocean in the middle of this time, we chose Tan My village (Quang Ngan commune, Quang Dien district - more than 15km north of Hue City) to enjoy the rustic, close and serene beauty of nature which is typical of the coastal village of Thua Thien on the other side of Tam Giang lagoon.

Located downstream of the Perfume River, Ru Cha is a rare primeval mangrove forest that exists in Tam Giang lagoon. The forest belongs to Thuan Hoa village (Huong Phong commune), about 15km from the center of Hue city. The scenery here is like a picture of pristine, fresh and gentle nature, attracting all eyes.
