武承嗣
After Wu died in 635 CE, his two sons were rude to their stepmother; after Wu Zetian came to power, she banished her half-brothers from the imperial court. At the same time she named her sister Lady of Han's son Helan Minzhi as heir to her father. However, Wu Zetian became displeased with Helan Minzhi's conduct and sent him into exile where he died. Thereafter she recalled Wu Yuanshuang's son Wu Chengsi from exile and made him Wu Shiyue's successor.
