In the easily forgotten ending of the movie Wall Street, the protagonist Gordon Gekko described the basic story outline of tulip bubble that most people know:

"As early as the 7th century, the Dutch had a speculative fever, so that you could buy a beautiful house by the canal in Amsterdam at the price of a tulip. They call it' tulip mania'. "

Gekko's words made us realize that tulip mania is now considered as a group illusion. The popularity of tulips quickly reached a fever pitch, so that even the price of tulip bulbs began to soar. Tulip bulbs can be resold dozens of times before they actually change hands, so the price of some bulbs is finally the same as that of luxury houses.
