One day, the collector went to the market to hang out. In an obscure corner, a piece of porcelain deeply attracted his attention.
   “How much?” The collector asked the owner of the porcelain casually.
   “Ten Yuan.”
   The collector shook his head and left.
  A few days later, the collector saw the piece of porcelain again at the market.
   He looked at the dust on the porcelain and couldn’t help leaning over to wipe it.
   “Mr. Five Yuan.” This time, the owner of the porcelain said remarkably.
   The collector hesitated and left.
  One day after half a month, the collector almost regretted his intestines…
   That day, the collector went to the market again. Old and distant, the owner of the porcelain ran to him with a smile and greeted him: “Sir, that porcelain was bought by a fool, 50 yuan!”
   Collector was almost shocked, almost fell, muttered to himself Say: “Fool, fool!”
