Diagramma degli Otto Trigrammi su Manoscritto Antico

A traditional Chinese Eight Trigrams (Bagua) diagram showing both the Earlier-Heaven and Later-Heaven arrangements, accurately matching the positions and characters from the reference image. Clear Chinese calligraphy and precise trigram line symbols arranged in circular formations. The background features an aged ancient manuscript texture with weathered parchment paper and subtle ink wash effects. Strict constraints: no pinyin, no Latin letters.
