如鱼得水 第1期

This idiom comes from History of the Three Kingdoms・Kingdom of Shu・Biography of Zhuge Liang. During the end of the Eastern Han Dynasty, it was great disorder under heaven and a host of forces appeared one after another. Liu Bei went to Liu Biao for shelter in Jingzhou when he was defeated by Cao Cao. In order to achieve a great task in the future, he recruited all kinds of quilified persons. Through the famous man Sima Hui's recommendation, Liu with his two sworn brothers, Guan Yu and Zhang Fei went to Wolonggang in Longzhong to visit Zhuge Liang, inviting him to help them. But unfortunately, they couldn't meet Zhuge at the first and second visits. Not until the third time, in a heavy snowstorm weather, did they finally meet Zhuge at his home. After Liu Bei made clear their intention. It made Zhuge deeply moved for their three visits. Then they made a penetrating analysis and discussed the situation seriously. Afterwards, Zhuge put forward a suggestion that Liu should first capture Jingzhou and Yizhou, then unite Sun Quan of Dong Wu to resist Cao Cao, and he also foretold that there would be the triangular balance of the power of the three kingdoms, Wei, Shu, and Wu in the world. Then Liu Bei had the highest esteem for Zhuge's ideas and appointed him as thc chief military adviser.

Since Zhuge was not only in a high post but also trusted so much by Liu Bei, which aroused Guan Yu, Zhang Fei and other generals dissatisfaction. Sometimes they also expressed their disagreements with Zhuge's military commands. They usually related their worries to Liu Bei, but Liu Bei, but Liu Bei paid no attention to them and said; "Having Kongming(another name of Zhuge Liang) to assist me, I feel just like a stranded fish which has been put back in the water. So I don't want to listen to anything more." From Liu Bei's metaphorical meaning, Zhuge Liang was the most important man to seize state power for him.

Now we use it to describe coming by somebody of one's taste or being in an environment appropriate to oneself.

此语出自《三国志・蜀书・诸葛亮传》。东汉末年，当时天下大乱，群雄纷起。刘备攻打曹操失利，投奔荆州刘表，为了日后成就大业，多方搜罗人才。经荆州名士司马徽的推荐，他特意拜访隐居在襄阳城西隆中卧龙岗的诸葛亮，请他出山。刘备带着关羽、张飞连去两次都未见着诸葛亮，直到第三次，在大雪纷飞时再去拜访才见了面。刘备说明来意，三次拜访使诸葛亮深受感动。他和刘备分析了形势，提出了夺取荆州、益州，东联孙权共同伐曹的战略方针，并预言天下将形成蜀、魏、吴三足鼎立的局面。于是刘备拜孔明为军师。

刘备对孔明的重用和信任，引起了关羽、张飞等将领的不满。他们有时也对孔明在军事上的指挥不满，经常到刘备面前诉说，可刘备却对他们说：“孤之有孔明，犹鱼之有水也，愿诸君勿复言。”意思是把自己比作鱼，把孔明比作水，说明孔明对自己夺取天下、成就大业的重要。
