臉上一塊青斑，刀裡藏著北斗七星

Traditional Chinese ink painting of Yang Zhi from Water Margin, a lean warrior clad in Song-dynasty armor. A massive oval celadon-green birthmark (pure #7BAEA0) covers roughly 60% of his left face. He wields an ancestral broadsword inlaid with 7 steel stars arranged in a Big Dipper pattern, its blade caught mid-swing as it slices through a snowstorm gust. Behind him, a blizzard-swept market scene holds a frozen "天漢橋" plaque, with the celestial 36 Stars manifesting as drifting ice crystals. Render the linework with sharp, iron-wire brush strokes and the birthmark with a splashed-ink technique, set against a high-contrast palette of celadon against obsidian-black (#2C2C2C). --no patterns facial-hair --ar 3:4 --style raw --v 7 --quality 2 --stylize 250
