Zhang Tianxi
In 363, Princess Dowager Ma died, and Zhang Xuanjing honored Lady Guo as princess dowager. She became concerned that Zhang Tianxi was acting dictatorially, and she conspired with the high-level official Zhang Qin () to kill Zhang Tianxi, but the news leaked, and Zhang Qin and other conspirators were put to death. Zhang Xuanjing became fearful and offered to yield the throne to Zhang Tianxi, but Zhang Tianxi refused. A month later, however, he had Liu Su lead soldiers into the palace to assassinate the 13-year-old Zhang Xuanjing, but claimed that Zhang Xuanjing died of an illness. Zhang Tianxi took the throne himself.
