刘据
The deposition of Empress Chen had left the position open, and Emperor Wu now had no official principal spouse. In 129 BC, Wei Qing, who was already a member of Emperor Wu's "insider circle" (內朝) of government officials, led an army of 10,000 cavalry and scored the first proper Han victory against Xiongnu. The following year, Consort Wei gave birth to Emperor Wu's first son, Liu Ju, and the overjoyed Emperor Wu (who was already 29 years of age when the son was born) immediately made her empress later that year. Liu Ju was later created crown prince in 122 BC.
