The 8-stroke left side — historically related to the early-morning glyph also seen in
朝 zhāo and
乾 gān. In
韩 it provides the syllable hán (drifted from gàn / hàn series). Visually it stacks
十 +
日 +
十 vertically; it has no productive standalone use today and is best memorised as the 'left side of
韩,
朝,
乾'.
