Chen Guangbiao [L] uses a hammer to smash an electric moped with a lead acid storage battery to draw attention to lead pollution.

Chen said the air is put into pull-tag cans he invented, with a chip in each can. The air is not compressed - he said his staff need only swing their hands three times to push the air into the can. When there is enough air, the chip will make the cap close automatically, he said.

He said each can contains negative ions like the oxygen from cylinders for medical uses.

"Open the can and three deep breaths will allow you to have a good mood and a clear mind," he said.

Chen's idea of selling fresh air received some negative feedback online as many said he was just showing off, like when he sings while handing out sheep, pigs and tractors to poor farmers.

Many microblog users said Chen is crazy to sell air since air can't be sold because it doesn't belong to anyone. Smashing the moped also was criticized since it is an economical means of transportation used by workers, and many said Chen should target bigger polluters.
