解放前，有人在上海开了一个帽子铺，并在门前挂了这样一块牌匾：盛锡福帽商制作并出售帽子收现钱。在征求朋友们的意见时，第一个朋友说，“帽商”二字显得多余，店主就把它去掉了。第二个朋友说：“收现钱”也没有必要，因为谁也不会赊帐买你的帽子。于是，店主也把它去掉了? Before liberation, someone opened a hat shop in Shanghai and hung a plaque in front of the door: Sheng Xifu hat merchants produced and sold hats to collect cash. When soliciting opinions from friends, the first friend said that the word “hat merchant” appeared superfluous and was removed by the shop owner. The second friend said: “Cash of cash” is not necessary, because no one will write off your hat. So, the owner also removed it?
