有则寓言说鲁国有个会织麻鞋的人,准备举家迁移到越国去,有人劝他千万别去,说是越国大多数人都打赤脚,且留下了“以子之长,游于不用之国,欲使无穷,其可得乎?”的忠告。到了近代,美国有家鞋厂派3名推销员到太平洋的一个岛屿去开辟市场,也发现这里的人不穿 There are parables saying that people in Lu state have woven hemp shoes and prepared to move their family to go to Yueguo. Someone advised him not to go. He said that most of the people in Vietnam have barefooted and left behind their children. The best of them is to swim in a country where you don’t use it. To make it infinite, it’s a good advice. In modern times, the United States has sent three shoe salesmen to an island in the Pacific Ocean to open up the market, but also found that people here do not wear it.
