不说功劳，也有苦劳

The old servant followed Mr. Wang for more than 20 years, not to mention credit, but also hard work, so at the end of the parting, Mr. Wang gave him a large sum of money, let him go home to old age.

Xiao Li worked very hard, he felt that he did not say credit, but also hard work, asked the boss to promote him, did not expect the boss to promote a young man who had just come to the company, which made him very disappointed.

As the saying goes, not to be credited, there is hard work, although her achievements in recent months are not significant, but the boss considered that she worked harder than anyone else, so still gave her a reward.
