The man who sells air
As is known, China is among the countries with the most air pollution.
A Chinese porter came up with an idea that seemed to work only in China,
And he made cans filled with clean air, and that's how people go around in China
They drink air. By the way it was a hit and millions of cans were sold
In a few days.
