Liu Rong

Liu Rong (Chinese: 劉榮) was the eldest son of Emperor Jing of the Han dynasty. He was made crown prince of the empire under the formal title Crown Prince Li (栗太子) in 153 BC but demoted three years later to Prince of Linjiang.
He was imprisoned in 148 BC for trespassing on the grounds of the temple of the Emperor Wen while building walls for his own palace. He was ultimately forced to commit suicide by the official Zhi Du (郅都). His grandmother, the Dowager Empress Dou, later had Zhi Du executed for a minor offense.
