Zhang Tianxi
In 361, Song Hun grew ill, and Zhang Xuanjing and Princess Dowager Ma visited him personally, asking whether his son Song Linzong (宋林宗) should succeed him if he died. Song Hun noted that Song Linzong was young and weak in personality, and that Song Cheng might be an appropriate choice—but also warned that Song Cheng's reaction was slow and needed to be watched closely. Song Hun warned Song Cheng and his own sons that they needed to be humble and faithful to the state, and he told many officials the same. He soon died, and it was described that the commoners on the street were all mournful and weeping. Song Cheng became regent, but just several months later, the general Zhang Yong (張邕), who was unhappy that Song Cheng became regent, overthrew Song Cheng and slaughtered the Song clan. Zhang Yong and Zhang Xuanjing's uncle Zhang Tianxi served as coregents, and soon Zhang Tianxi killed Zhang Yong (claiming, inter alia, to be avenging the Songs), but eventually overthrew Zhang Xuanjing himself in 363 and took the throne.
