In 191 BC, at Lü Zhi's insistence, Emperor Hui married his niece Zhang Yan (Princess Yuan of Lu's daughter) and made her empress. They did not have any children. It was alleged that Lü Zhi told Zhang Yan to adopt eight boys and have their mothers killed. There is uncertainty whether these children were Emperor Hui's; the traditional view is that they were not, while modern historians believe that they were born to his concubines.
