Yu Zhengfu, 64, a resident of the Inner Mongolia autonomous region, brought his fight against drugs to Xining, Qinghai, on Wednesday, when he arrived aboard his aircraft-like motor tricycle. The tricycle is both his vehicle and bedroom.

He started his odyssey against drugs in 2003. During the past four years, he has visited 28 cities, including Shanghai and Hong Kong.

The only hitch on his journey so far came in the form of his ex-wife, who divorced him after he launched the campaign.
