The first story is "Quick Man Tan". He hepled a man who had pointed a knife on his face just like a wheel.

The second story is "The Wheel on the Wall". It is an old wooden wheel sits on English pub.

The third story is "Special Clay". Americans young man made the wheel.

The fourth story is "The Trishaw Man", He dorve people around on a three-wheeled trishaw bicycle.

The fifth story is "Beautiful Thing" that is the strange wheel thing. But, I didn't understand connectiron their stories means and the book's title.
