A successful businessman was invited to a TV
 . Everybody couldn’t wait to hear a success story from him. He, however, only said  , “Won’t it be better for me to ask you for help on a certain problem？”
Here was his problem. “ People all rushed to the place where a gold mine(矿) had just been    , but there was a deep river stopping them. They must cross the river if they wanted to get to the gold mine. What would you do if you were among them? Please give me some  .”
