Liu Ju
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.
