King Zhaoxiang of Qin
Because King Zhaoxiang had not yet legally come of age (traditionally at the age of 20), his mother, who was now known as Queen Dowager Xuan, became the regent. She was supported by her brothers, Wei Ran and Mi Rong (羋戎), as well as two other sons, Prince Yi (公子悝) and Prince Fu (公子巿), the four of them collectively known as the "Four Nobles" (四貴).
King Zhaoxiang of Qin
Bai Qi wanted to take advantage of the victory at Changping and immediately lay siege to the Zhao capital of Handan (邯鄲). This frightened the states of Zhao and Han greatly, so they sent Su Dai (蘇代, Su Qin's brother) to bribe Fan Ju (范雎, or Fan Sui 范睢), who was then the Qin chancellor and jealous of Bai Qi's military achievement. Fan Ju persuaded King Zhaoxiang to halt the offensives, citing as the reason that the soldiers needed to rest after years of war. Qin agreed to an armistice in exchange of the states of Zhao and Han conceding lands.
