The fraternal relationship between Emperor Cheng and Prince Kang was quite affectionate, notwithstanding the succession struggle, and Prince Kang was often summoned to the capital Chang'an to accompany Emperor Cheng, who was sonless. Prince Kang was viewed by many as the potential heir – a status that was greatly despised by Emperor Cheng's uncles from the Wang clan. Consort Fu was happy to see this situation develop. In 24 BC, however, under pressure from his uncles, Emperor Cheng was forced to send Prince Kang back to his principality, and it would appear that the brothers did not see each other again alive, as Prince Kang died in 23 BC and was succeeded by his son Prince Xin.
