There was a famous scholar called Gongsun Long from the State of Zhao during the Warring States Period (475-221BC). Keeping a circle of skilled people around him, he often said, "A wise man will welcome anyone with a specialty."
One day, a man dressed in tattered and dirty clothes came to visit him and recommended himself: "I have a special skill." Gongsun Long asked, "What is it?" The man answered, "I have a very loud voice and I'm good at shouting." Then Gongsun Long turned to his followers and asked, "Is there anyone who is good at shouting?" But none of them answered yes. So the scholar took the man in.
Some days later, Gongsun Long and his followers went on a trip. They came to a wide river and found the ferryboat was on the other side of the river. All of them had no idea about what to do. It suddenly came to Gongsun Long's mind that the man he just took in was good at shouting, so he turned to the man and asked, "Can you shout loudly at the ferryman so that he may get us?" The man realized it was the chance to show his skill. He shouted to the ferryman as loudly as he could, "Hey, ferryman, come here! We want to cross the river." As his voice ended, the ferryman rowed the boat towards them. Gongsun Long was very satisfied with his new follower.
Later, people use the phrase, "yī jì zhī cháng" to describe anyone who has a special professional skill.

一技之長
?????? 戰國時期，趙國有位名士叫公孫龍。他手下聚集了許多有自己特長的門客。他常說：“一個聰明人應該善于接納每一個有自己特長的人?！?/p>
?????? 一天，有個穿著很破爛的人來見他，并向他推薦自己：“我有一項特別的本領?！惫珜O龍就問道：“什么本領？”那個人回答道：“我聲音特別大，很善于叫喊。”公孫龍聽了，就轉身問他旁邊的門客：“你們有誰善于叫喊？”結果沒有一個人回答“是”。于是，他就收下了這個很善于叫喊的人作他的隨從。
?????? 沒過多久，公孫龍和他的門客一起出外游玩。他們來到一條很寬的河邊，發現渡船在河的另一頭，所有人都不知怎么辦好。突然，公孫龍想起他最近收的那個人的本領是善于叫喊，于是，他就轉過頭去對那人說：“你大聲叫對面的船夫，看能不能把他叫過來。”那人覺得展示他技能的時候到了，就盡力大聲向對面喊：“喂，船夫，過來，我們要過河?！碑斔新晞偼辏菍γ娴拇蚓蛽u著船過來了。公孫龍對這個新收的門客非常滿意。
?????? 后來，“一技之長”就用來形容一個人有一項特殊的本領。
