The name Chac Chan is based on the Vietnamese word chắc chắn and means firm. It also has the meaning of lasting or sustainable.
On one of the photos Chac Chan is combined with two other brown sculptures from the series Treasures of Earth: Da Song and Kho Bau. The shapes of the different sculptures get stronger when being put together, just as the karst mountains have this influence on each other. On this image the three sculptures are still unglazed.
