Deng Xiaoping's contributions to Reform and Opening Up cannot be overlooked.
Tips
usage
Literally 'merit (功) cannot (不可) be erased (没).' 没 here is read mò 'to drown/efface,' not méi. The idiom is used to give explicit credit, often when summing up someone's role in a collective achievement.
mistakes
Don't read 没 as méi here - it's mò ('to submerge/erase'). Reading 功不可méi would change the sense to 'merit cannot be lacking,' which is wrong.
