were also well rewarded, including the decreed marriage of Wei Shaoer's older sister Wei Junru () to Emperor Wu's adviser, Gongsun He (). At the time, Wei Shaoer was romantically engaged with Chen Zhang (), a great-grandson of Emperor Gaozu's adviser Chen Ping. Their relationship was also legitimized by Emperor Wu through the form of decreed marriage. Through the rise of the Wei family, the young Huo Qubing grew up in prosperity and prestige. Military career Huo Qubing exhibited outstanding military talent even as a teenager. Emperor Wu saw Huo's potential and made Huo his personal assistant. In 123 BC, Emperor Wu sent Wei Qing from Dingxiang () to engage the invading Xiongnu, and appointed the 18-year-old Huo Qubing to serve as the Captain of Piaoyao () under his uncle, seeing real combat for the first time. Although Wei Qing was able to kill or capture more than 10,000 Xiongnu soldiers, part of his vanguard forces, a 3,000-strong regiment commanded by generals Su Jian (蘇建, father of the Han diplomat and statesman, Su Wu) and Zhao Xin (趙信, a surrendered Xiongnu prince) was outnumbered and annihilated after encountering the Xiongnu force led by Yizhixie Chanyu (). Zhao Xin defected on the field with his 800 ethnic Xiongnu subordinates, while Su Jian escaped after losing all his men in the desperate fighting. Due to the loss of this detachment, Wei Qing's troops did not earn any promotion, but Huo Qubing distinguished himself by leading a long-distance search-and-destroy mission with 800 light cavalrymen, killing the Chanyu's grandfather and over 2,000 enemy troops, as well as capturing numerous Xiongnu nobles. A very impressed Emperor Wu then made Huo Qubing the Marquess of Champion () with a march of 2,500 households. In 121 BC, Emperor Wu deployed Huo Qubing twice in that year against the Xiongnu in the Hexi Corridor. During spring, Huo Qubing led 10,000 cavalry, fought through five Western Regions kingdoms within 6 days, advanced over 1,000 li over Mount Yanzhi (), killed two Xiongnu princes along with nearly 9,000 enemy troops, and captured several Xiongnu nobles as well as the Golden Man idol used by Xiongnu as an artifact for holy rituals. For this achievement, his march was increased by 2,200 households. During the summer of the same year, Xiongnu attacked the Dai Commandery and Yanmen. Huo Qubing set off from Longxi (modern-day Gansu) with over 10,000 cavalry, supported by Gongsun
