The sudden rise of a love rival enraged Empress Chen, but she could do little as Wei Zifu was now under the Emperor Wu's direct protection. Princess Guantao then tried to seek vengeance for her daughter, and after finding out that Wei Zifu had a half-brother named Wei Qing (衛青) serving as a horseman in Jianzhang Camp (建章營, Emperor Wu's Royal Guards), she sent men to kidnap and murder Wei Qing. However, Wei Qing was rescued by his friends, a group of palace guards led by Gongsun Ao (公孫敖), who also reported the whole incident to Emperor Wu. As a sign of annoyance towards Empress Chen and her mother, Emperor Wu publicly made Wei Zifu a consort (夫人, a concubine lower only to the empress), appointed Wei Qing to the Chief of Jianzhang Camp (建章監), Chief of Staff (侍中) and Chief Councillor (太中大夫), promoted several other members of the Wei family, and rewarded everyone who contributed to Wei Qing's rescue. Consort Wei Zifu then went on to monopolize Emperor Wu's love for over a decade and bore him three daughters.
