When Wang Mang's powerful uncle, Wang Feng (王鳳, commander of the armed forces (33 BC-22 BC) grew ill, Wang Mang cared for him day and night and attended to his medical and personal needs. Wang Feng was greatly touched, and before his death, he asked Empress Dowager Wang and Emperor Cheng to take good care of Wang Mang. Wang Mang was therefore given the post of imperial attendant (黃門郎) and later promoted to be one of the subcommanders of the imperial guards (射聲校尉).
