Once Mozi went to Qi in the north. He met a person named Ri. Ri told Mozi that, "You cannot head north today. It is unlucky for dark-skinned person to head north, because the emperor of the heaven is killing the black dragon." Mozi did not believe him and continued to head north.
Later, Mozi went back. Ri said to Mozi proudly, "How is that? I told you that you cannot head north. Did you meet some troubles?" Mozi smiled, "The flood made it impossible for the people in north and in the south to move. There are people with dark skin and there are people with fair skin. Why all of them cannot go through?" Ri could not answer. Mozi said, "Suppose the emperor of heaven killed the green dragon in the east, the red dragon in the south, the white dragon in the west. Then people all over the world cannot move. Therefore, your lies cannot compete with my truth. It is like throw eggs at rock. Even all the eggs in the world are used up. The rock will still remain unbroken."
"以卵击石" refers to throw eggs at rock. It means that the strength of the two parties is greatly uneven. The weak party did not estimate its strength correctly and insist on fight against the strong party and would lead only to ruin.
例句:
1、你们公司跟他们公司抢这个项目,简直就是以卵击石。 You company is fighting against their company for this project. It is to throw egg against rock.
2、敌军力量比我们强大得多,如果我们硬拼,无异于以卵击石。 The enemy army is much stronger than us. If we fight recklessly, it is to throw egg against rock.
