Liu Sheng
In the third year of the reign of Emperor Wu, his younger brother, Liu Sheng and several other princes were invited to Chang'an to feast; at the feast Liu Sheng wept and complained of the treatment of the feudal princes by centrally appointed officials, who made use of their role as monitors to constantly trump up charges against the princes. Impressed by this petition the Emperor explicitly ordered that the unfair scrutiny of the princes should stop, and Liu Sheng became one of the most renowned of the feudal rulers of his time.
