趙王
Lü Zhi also played a role in the death of another of Gaozu's sons, Liu You, the Prince of Zhao. Liu You married Lü Zhi's niece but was caught having an affair with another woman, so Lü Zhi's niece reported to her aunt that Liu You was plotting a rebellion. Lü Zhi summoned Liu You to Chang'an and had him imprisoned and deprived of food. Liu You was afraid of committing suicide and eventually starved to death, in 181 BC.
