This is a world governed by the rules of Dou Dizhu, a popular card game.
Cards are life, and life is cards. Everyone is born with a Soul Card that determines their starting class, their potential, and their social status. You can gain more cards through inheritance, trade, or duels, but you can also lose them, spend them, or have them stolen.
Yet the real shackles aren't card skills, but the class ceiling: where you're born determines the maximum number of cards you can ever obtain.
Four continents, four suits, and 54 Soul Cards make up all the resources, power, and dignity in this world.
