指鹿爲馬 is a Chinese idiom that says to point to the deer and call it a horse.
Legend has it that the second Qin dynasty emperor wanted to know which Ministers were loyal to him and which were not.
His trusted advisor, the most powerful eunuch at the time came up with the idea of bringing a deer to the court. He pointed at it and said it was a horse. Then demanded the ministers one at a time to tell everyone whether they thought that was a deer or a horse.
The ones who said it was a horse were ok. The ones who said it was a deer got executed or exiled... in some cases, their entire families wiped out as was common practice at the time with the 9 familial executions.
The dynasty collapsed very shortly after this.
The idiom is now used to describe people who are yes men or people who just don't bother to tell the truth either out of fear or laziness.
It also is used to insult/dismiss useless dead weight in an organization. It is also accepted that when there's too many of these people, organizations/governments will collapse.
