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.

At the seminar "Hollowness and Open Space of the City" jointly organized by ASHUI, Tich Thien Vien and Thua Thien Hue Association of Architects, speakers and architects with diverse perspectives exchanged many interesting stories and experiences about gardens and open space inside houses and the “hollow and open” space within the city.
