Chinese entrepreneur Chen Guangbiao has launched a line of canned air for the Chinese market, to give people something to breathe that isn’t the smog-filled Beijing air. Guangbiao, a billionaire who has become known for his stunts, is selling the product to bring more attention to the problems of pollution in China: It comes with atmospheric flavours including pristine Tibet, post-industrial Taiwan and revolutionary Yan’an, the Communist Party’s early base area.
