The external quality of the exhibition centre is generated with the location on a slope with an altitude difference of approximately 45 m. The Convention and Exhibition Centre resting on a hill radiates the self-confidence and cosmopolitan attitude of a fast growing metropolis. This effect is enhanced towards the outside with the special effect of the domical roof, its axis being directed towards the city. The shape of the translucent dome is reminiscent of an opening blossom, which has become the symbol of Nanning, and therefore defines a new symbol of the city.
The access from the centre is provided via a pedestrian bridge from the exhibition square. Starting from the entrances, comfortable flights of stairs and escalators lead to the four flexibly usable exhibition levels and to a generous entrance fore-court. The exhibition halls are located on both sides along the two-storeyed foyer and can on all levels be flexibly interlinked as groups. The exhibition foyer and the upper exhibition halls are all covered by a common roof structure.
The multi-functional large hall with its folded domical roof and an overall height of 70 m and a hall diameter of 48 m forms the head of the complex and protrudes the city silhouette as a landmark. Its form is created from a filigree steel framework, being covered with a translucent, thermally insulating membrane. This allows a diffuse light to shine through to the city and the surrounding area at night and the "roof crown" above Nanning radiates.
