以假乱真

以假乱真:

Literally means:

mix the false with the genuine

Actually means:

something looks too real to be fake

It means making it difficult for others to tell the fake from the genuine by mixing them together.

Sometimes this phrase means that the counterfeit looks so real that people may take it as genuine. Sometimes it indicates deliberate cheating, and is derogative.

把假的当作真的，使人真假难分。

有时用来说明模仿的事物逼真，使人认为是真的。有时表示故意骗人，这时具有贬义。
