Who is the hero who just filled in the blanks?

The hero who makes up the numbers is Chu Shi from the south, which comes from the historical allusions in the Warring States period.

Indiscriminate: indiscriminate; Cuan: an ancient musical instrument; Crime: impersonation; Numbers: Numbers.

Literally:

People who can't play the flute are mixed in the flute team. To make a metaphor, people who have no real talent and practical learning mix a number among experts, or to make a metaphor, grasp the bad things and mix them in the good ones. Sometimes it is also used to express self-modesty, saying that you are not good enough and just make up the numbers.

Original text:

It is a person who plays this space. There must be 300 people in this art troupe. Nan Guo invited him to play the piano. He was very happy to hear that hundreds of people supported him in the Zhou Dynasty. After Qi Xuanwang's death, King Qi Huan acceded to the throne. He liked listening to a play very much. When Nan Guo heard about it, he ran away. Excerpted from Everything is Wrong, Hidden Theory.

Expose the truth:

The story of fiddling tells people that fraud can't stand the test of time and will eventually expose the clues. If a person, like Mr. Nan Guo, can't blow the whistle, has no real skills and just pretends to be scary, he can get away with it for a while when others don't know the truth, but the truth will come out one day.
