Beijing’s Mayor Wand Qishan is against the use of billboards to luxury products, saying that they will increase the hostility between the rich and the poor. Most common luxury products displayed in billboard ads are apartments, villas, automobiles and other luxury goods. There is a wide gap between the rich and the poor in Beijing, with the average income coming to 5,900 yuan or USD765 in this years first quarter. Rural residents make less than this amount.
