A hand-drawn educational

A hand-drawn educational mind map illustration on a white background. In the center, a cute black and white ink sketch of an ancient Chinese scholar wearing Hanfu robes, holding a small tea cup, standing on a large vertical tea stalk. The tea stalk branches out into organic, tree-like limbs extending to the corners. The branches are decorated with doodle icons representing tea science: water droplets (representing moisture), simplified chemical molecular structures, leaves, small flowers, and sun icons. The style is minimalist, sketch-notes style, marker pen texture, clean lines, high contrast. No text, leave blank spaces on branches for writing.
