随着社会的高速发展，城市化和工业化的不断扩大，导致空气严重的被污染。作品选用北京、武汉、西安这三座城市名的汉字，将雾霾颗粒抽象放大成不同的圆点附着在汉字上，露出极少能见的笔画，背景隐现着颗粒状组成标志性的城市建筑天坛、黄鹤楼、大雁塔。寓意雾霾不断的笼罩着这座城市，侵害人民身体健康。

With the rapid development of society, the continuous expansion of urbanization and industrialization leads to serious air pollution. The work selects the Chinese characters of the names of cities Beijing, Wuhan and Xi 'an，and the smog particles are abstracted and enlarged into different dots attached to the Chinese characters, showing some visible strokes. The grainy compositions of the iconic city buildings the Temple of Heaven, Yellow Crane Tower and the Great Wild Goose Pagoda are looming in the background. It implies that the haze constantly envelops the city and harms the health of people.
