The literal translation of the title of this movie is: The Number One Case of the New China.
This movie is based on the true story that really happened in the early 1950's. It was about the corruption case of two corrupted officials who embezzled public funds, and accepted bribes, and used drugs. They were eventually caught and tried, and executed in public. The movies give an accurate depiction but without one most important fact:
As a result of this corruption case, the anti-corruption law established that any corrupted officials would be executed if the total amount of money or material they steal is more than 1000 bucks. Compared with the current rampant corruption in China where corrupted officials steal tens of millions of bucks and still get away with it by escaping death and life sentences, it is not surprised the Chinese governmental censorship forced this part to be eliminated because including this historical fact would make the current regime impossible to face the public.
