High profile businessman Chen Guangbiao sells his cans of air for 50p each, which come in flavours including pristine Tibet, post-industrial Taiwan and revolutionary Yan’an, the Communist Party’s early base area.

“If we don’t start caring for the environment then after 20 or 30 years our children and grandchildren might be wearing gas masks and carry oxygen tanks,” said  Chen.

Earlier this month the concentration of airborne PM 2.5 particulates in Beijing and other cities in the region reached the highest levels since measurements began. Hospitals reported a sharp rise in respiratory-related admissions and visibility dropping as low as 200 metres several times in the past few days.
