Hauling a large refining unit over a bridge.<br />
Then came another contradiction, that between the<br />
load limit of an ordinary bridge and the great weight of<br />
big equipment loaded on the big trailer truck. Once when<br />
we were taking a 120-ton item to an engineering project,<br />
we had sixteen concrete bridges to cross. Each had a<br />
load limit of thirteen tons for trucks and sixty tons for<br />
caterpillar tractors. How were we to get our 120-ton<br />
load over them? Some bridge engineers and technicians<br />
said it couldn't be done, that the bridges would give way.<br />
We decided to analyse this contradiction before trying to<br />
find a solution. Chairman Mao says: "When we look<br />
at a thing, we must examine its essence and treat its<br />
appearance merely as an usher at the threshold, and once<br />
we cross the threshold, we must grasp the essence of the<br />
thing; this is the only reliable and scientific method of<br />
analysis."<br />
