Baoshi is fake, but the collected physical evidence is real. Bao Gong took advantage of the fact that the stolen goods (oil stains) and the accessories of the basket (oil stains) were the same, and soon solved the case. Therefore, what Bao tells us is to have flexible thinking when solving problems.
One day, a child was watching a play on a stone after selling fried dough sticks, and the basket containing fried dough sticks was placed on the next stone. After watching the play, the child found that the copper coins in the basket were gone, and the child sat on the ground crying. Bao Gong happened to pass by. After asking about the situation, he said that he would interrogate the stone that stole the child's money. Bao Gong ordered the stone to be carried to Kaifeng for a public trial.
