In 128 BC, Consort Wei Zifu gave birth to Emperor Wu's first son, Liu Ju, and was created Empress very soon after. Later that year, Wei Qing, who was now officially a trusted member of Emperor's extended family, led 30,000 cavalry from Shanwu (near present-day Youyuxian, Shanxi) in Yanmen Commandery, killing thousands of Xiongnu soldiers.
