In the Asian worldview, the relationship between Heaven - People - Earth is connected through the animal and plant world, with countless sacred human concepts to ward off evil spirits and pray for peace for people and all things. Among them, the Four Sacred animals (Dragon, Unicorn, Turtle, Pheonix), starting from the Dragon, symbolize the strong desire of the Creation and the traditional beliefs to pray for agricultural residents' good harvests, good weather, and dispelling epidemics.

The dragon, known by the character "long", is a mythical creature steeped in supernatural qualities, standing at the forefront among the four sacred animals: "dragon, unicorn, tortoise, phoenix". It emerged thousands of years before the Common Era, gradually elevated to a symbol in East Asian culture. The dragon is seen as the ruler governing the rivers and seas, often referred to as the Dragon King.

From an endemic creature known as an Asian unicorn, the saola (Pseudoryx nghetinhensis) is grabbing more attention from the community. Aside from becoming the mascot in the 31st SEA Games, the image and name saola also become a business brand in many fields.

That was the theme of the Saola (spindlehorn or Asian unicorn) exhibition in response to the World Saola Day July 9, which was held by the Provincial Forest Protection Department in collaboration with the World Wide Fund for Nature in Vietnam (WWF-Vietnam) at the Hue Children’s House on July 9.
