Emperor Yuan
As the princes further grew older, Emperor Yuan and Prince Kang became closer. They shared an affection for, and skills in music, particularly in the playing of drums. Prince Kang also showed high intelligence and diligence, while Crown Prince Ao was known for drinking and womanizing. When Emperor Yuan became seriously ill (c. 35 BC), Consort Fu and Prince Kang were often summoned to his sickbed to attend to him, while Empress Wang and Crown Prince Ao rarely were. During his illness, Emperor Yuan considered whether he should make Prince Kang his heir instead (apparently encouraged by Consort Fu) . Only the intercession of Shi Dan led Emperor Yuan to cease those thoughts. When Emperor Yuan died in 33 BC, Crown Prince Ao ascended the throne (as Emperor Cheng).
