下阳 / Xiayang (Chu-Han)
下阳 / Xiayang enters the wiki through Hanji 155-2 as the real crossing point 韩信 uses against 魏豹. While Wei concentrates near 临晋 and 蒲阪, Han Xin shifts north to Xiayang and crosses where the water is calmer.
The episode makes Xiayang a practical rather than decorative geography point. The hidden crossing works because soldiers can use wooden boards and jar-floats to move across the river, allowing the Han army to threaten 安邑 before Wei Bao can turn his frontal defense into a response.
