解放前，上海有一个叫盛锡福的制帽商。起初，他帽店的招牌是这样写的：“盛锡福帽商，制造并出售帽子，收现金。”第一个朋友看后，觉得“帽商”二字纯属多余，因为后面已有交代。于是盛老板去掉了这两个字。第二个朋友看后，觉得做生意收钱天经地义，没必要特别强调它，于是盛老板又去掉了“收现金”三个字。第三个朋友看后，觉得除“盛锡福”三字外，其余的字都显得累赘，不便传诵，建议也去掉。 Before the liberation, Shanghai had a cap maker Sheng Shengfu. At first, the signboard of his hat shop was written like this: “Shengxifu Hatter, who manufactures and sells hats, receives cash.” After seeing his first friend, he thought the term “hat merchant” was purely superfluous, as we have already explained. So Sheng boss removed these two words. After looking at the second friend, I feel that it is perfectly justifiable to do business and collect money. Therefore, Sheng boss has removed the word “cash withdrawal.” After looking at the third friend, I think except for the words “Sheng Xifu”, the rest of the words are cumbersome, inconvenient to chant, suggestions are removed.
