It is not known when exactly Consort Fu became a consort to Emperor Yuan, but it is known that it happened during his years as crown prince – but after his eventual wife Empress Wang became a consort of his. She and Consort Feng Yuan became his favorite concubines, and each of them bore him a son. Consort Fu's son was Liu Kang (劉康), who later was created the Prince of Jiyang, then Prince of Shanyang, then Prince of Dingtao. As Consort Fu's position was inferior to that of Empress Wang, and her son younger than Empress Wang's son Liu Ao (later Emperor Cheng), Prince Ao was created crown prince. However, Consort Fu was not content for her son merely to be an imperial prince, and a succession struggle would erupt.
