Empress Dowager Lü then went ahead and carried out her plan to make members of her clan princes. In summer 187 BCE, after her daughter, Princess Yuan of Lu died, she made the princess's son, Zhang Yan (張偃), Prince of Lu. Princess Yuan of Lu's husband and Zhang Yan's father, Zhang Ao (張敖), had, during Gaozu's reign, been Prince of Zhao, but was removed as part of the policy against non-Liu princes, so Empress Dowager Lü might have felt that making Zhang Yan a prince would be considered to be more justified; when Zhang Ao died in 182 BCE, he was posthumously honoured as a prince.
