The more one tries to cover up, the better-known it will become.
During the Spring and Autumn Period (春秋时期,770-476 BC), there lived a man named Hei Gung, who worked for the government
of the kingdom of Ju. Hei Gung once secretly
gave a piece
of Ju's territory
to the kingdom
of Lu, in the hopes that Lu would take him in.
Thinking that no one knew what he had done, he very quietly
moved to Lu, never dreaming that Lu would record this incident
in great detail.
Later, when the people of Ju realized
that Hei Gung had moved, they began to ask about that, and only then they learnt of the great dishonor
he had brought to his country.
Hei Gung never imagined
that so many people would find out about this thing which he didn't want anyone to know.
Today, this idiom is often used in situations in which a person tries to cover up a thing which he has done, but in doing so only makes his wrongdoing more obvious
英文中若要表达“欲盖弥彰”的意思，可以用短语“The more one tries to cover up, the better-known it will become.”。
