Although you are wronged at present, don't be too sad.
There is a public opinion in the world that right and wrong will be clarified after a long time (that is, people will see the truth clearly).
There are people in the world who distinguish right from wrong and uphold justice (they won't let grievances sink to the bottom of the sea).
There will be a turn for the better in the future.
This is a four-sentence signature, telling the people who draw lots that although they are wronged at present, this is only temporary and will definitely give the parties a fair deal in the future.
I don't know if there are too many villains or the backstage management is blind, but it doesn't mean that the above words are illegal.
