Shi Hu
In 348, after executing his second crown prince Shi Xuan (石宣) for having assassinated his younger brother Shi Tao (石韜) and for plotting against himself, Shi Hu considered whom to make his new crown prince. Zhang, believing that he could hold power jointly with Consort Liu if she were to become empress dowager, suggested to Shi Hu that the reasons why his prior crown princes rebelled was that their mothers were of low birth. Shi Hu agreed, and he created Shi Shi crown prince and Consort Liu empress.
