the sand table is in the hall on the first floor of the building. It is 8.55m long and 7.35m wide. It restores the urban pattern of Chang'an city of Tang Dynasty and is one of the important exhibition items of Ziyun building.The three sides of the sand table are three electric lifting curtains, each with an area of 8m * 3M. The three screens will be lowered during the performance to form a three fold screen; during the non performance time, the screen will automatically rise to present the golden statue of Emperor Xuanzong of Tang Dynasty located behind the sand table.

Using the building model on the sand table and three electric screens on the sand table, Wincomn has created an immersive three-dimensional sand table interactive projection show for it.
