One day, there was a blind man sitting on the steps of a building with a sign by his feet, that reads: "I am blind, please help."
A creative publicist was walking by the blind man and stopped to observe that the man only had a few coins in his hat. He put a few of his own coins in the hat, and without stopping to ask for permission（征求许可） , took the sign, turned it around, and wrote a new message. He then placed the sign by the feet of the blind man, and left.
Later that afternoon the creative publicist returned by the blind man and noticed that his hat was almost completely full of bills and coins. The blind man recognized his footsteps and asked if it was him who had changed his sign? He also wanted to know what the man wrote on it.
The blind man didn't know that his new sign reads as this: "It's spring now, but I can't see it."
