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
In 256 BC, a Qin general named Jiu (摎) attacked Han, killing 40,000 of the enemy and capturing Yangcheng (陽城) and Fushu (負黍). Two years later in 254 BC, Jiu attacked Wei and captured Wucheng (吳城), forcing Wei to submit to Qin as a vassal state.
