Generate a poster for the '{argument name="subject" default="Relationship Map of the 108 Heroes of Water Margin"}', using a Chinese classical ink wash combined with a modern infographic design style. With '{argument name="central figure" default="Song Jiang"}' as the central main node in the middle of the screen, the 108 heroes are distributed in a hierarchical radial pattern around him. The inner circle highlights the core 36 Heavenly Spirits, the outer circle shows the 72 Earthly Fiends, and the outermost circle includes the imperial court and villain forces, showing the opposition between Liangshan and the court. Use small portraits and nameplates to create a complete sense of the 108 heroes' array, and label the relationships between them. The overall structure is complex but clear, with a prominent center and distinct layers, reflecting the full relationship spectrum of '36 Heavenly Spirits + 72 Earthly Fiends + Imperial Forces'.
