Whose background is the "red sun, sea water, auspicious clouds" and "Kirin" behind the ancient official platform?

That's not a unicorn. It's called an armadillo.

The seventh of Longsheng's nine sons

The armadillo, also known as the Charter, looks like a tiger and is the old seven. It is litigious all its life, but it is powerful. The tiger head decoration on the upper part of the prison door is its portrait. Legend has it that armadillos are not only eager for public interests and justice, but also brave in speaking, able to distinguish right from wrong and judge impartially. In addition, its image is majestic, and the prisoners are not only decorated on the prison door, but also squatting on both sides of the official hall. Whenever the yamen chief is in court, there is an image on the title card and the silence card of the chief. It looks around and looks around, maintaining the solemnity and righteousness of the court.
