This is a bus stop advertisement in Beijing. It shows washing machines staked up to form the Great Wall of China. I think the creative concept here must have been to transfer the durability and strength of the Great Wall of China to the product’s brand. But I think there should be some national guidelines on how national symbols such as the Great Wall of China is used in commercial advertisements. Else everyone is going to start using the Great Wall of China for advertisements to promote cereals to shampoos.
