Learn Chinese with @cn-reader: All Dogs Have Their Days 士别三日

成语：士别三日（ shì bié sān rì）

Idiom: All dogs have their days.

Explanation: One has made great progress in a short period of time and should be treated differently.

Xiao Liu has just graduated from university and entered a fortune 500 company. When people enter the society at the very first place, there are always some uncomfortable places. Xiao Liu is a newcomer, and the cooperation with his supervisor Mr. Wang goes not so well. However, Mr. Wang happens to be a hot-tempered man. Under the pressure of intense work, he has no patience to teach Xiao Liu how to do the work. He just considered Xiao Liu was not suitable for the job.

After the probation period, Mr. Wang gave the opinion that Xiao Liu was not qualified for the job and refused to accept the offer. However, the human resources department has a good impression on Xiao Liu, who is a loyal and steadfast young man. They wanted to give him another chance, so they transferred Xiao Liu to a branch office in another city.

With a depressed mood, Xiao Liu went to another branch of the city. This time, his supervisor Mr. Zhao is a highly skilled and benevolent person. Mr. Zhao has his own set of teaching methods, and he often helps Xiao Liu with his work. Xiao Liu is a studious young man. With the help of Mr. Zhao, he made rapid progress and his performance improved rapidly.

Three years later, Xiao Liu has been promoted to department manager in the branch company, and he is the youngest leader among middle managers. Not long after, the team led by Xiao Liu became the most outstanding department in the company.

At the annual meeting, Xiao Liu made a statement of performance analysis. His former supervisor Mr. Wang also attended the meeting. He was surprised and embarrassed to see Xiao Liu's progress, for Xiao Liu was now more senior than he was. Xiao Liu did not mind it at all. He said that he was growing up in the effort, and hoped Mr. Wang could no longer treat him as he used to.

Nothing is set in stone. Now, we use this idiom to describe rapid growth and progress in a short period of time.

解释：比喻即使三日不见，别人已有进步，即不能再用老眼光去看人。出处：《三国志·吴志·吕传》注引《表传》：“士别三日，即更刮目相待。”

小刘大学刚毕业，进入了一家五百强企业工作，新人刚进入社会，总有一些不适应的地方，小刘是新人，和上司王主管的配合也没有磨合完善，有时候工作起来并不是太顺手。而王主管呢，偏偏是位急脾气的人，在强大的工作压力下，也没有耐心去教导小刘应该怎样做，只是认为小刘不适合这份工作。

试用期后，王主管给出的意见是小刘不能胜任工作，拒绝录用，但人力资源部招聘的时候却对小刘印象不错，比较认可这个为人忠诚踏实的小伙子，便想再给他一个机会，于是便把小刘调动到了另一个城市的分公司去工作。

小刘怀着郁闷的心情来到了另一个城市的分公司，这次他的上司是位业务能力很强，为人也很亲善的赵主管，赵主管对新人有自己的一番教导方式，经常为小刘提供一些工作上的帮助。小刘其实也是位好学进取的小伙子，在赵主管的帮助下，成长迅速，业绩也突飞猛进的发展起来。

三年后，小刘在分公司中已经晋升成为了部门经理，是中层管理者中最年轻的一位领导。没过多久，小刘带领的团队，就成为了全集团中业绩最突出的部门。

在年终的集团总部召开的表彰大会上，小刘代表分公司做了业绩分析的发言，当年的王主管也参加了会议，见到小刘的崛起，十分诧异和不好意思，毕竟小刘现在的职级已经比他要高了。小刘倒是不介意，笑谈中表示自己是在不断努力中成长起来的，王主管可不能再用当年的目光来看待自己了。

所以说，没有什么是一成不变的，我们如今用这个成语来形容短时间内迅速的成长和进步的事物。
