韩婴 / Han Ying
韩婴 / Han Ying enters the wiki through 《资治通鉴·周纪》60丨 中国第一位把持朝政的太后竟是她？ as the 韩国 crown prince who meets 秦昭襄王 and 魏襄王 at 临晋 in 302 BCE. The episode then has Han Ying visit 咸阳 before returning home.
His source role is diplomatic rather than biographical. The meeting and Xianyang visit mark Qin’s effort to repair relations with Han and Wei after the 芈横 hostage incident breaks Qin’s 楚国 alignment and makes a future attack on Chu more likely.
