張祚
Most historical sources indicate that Zhang, like his grandfather Zhang Shi (), his granduncle Zhang Mao, and his father Zhang Jun, continued to use Emperor Min of Jin's era name "Jianxing" (both to show continued allegiance to Jin and to distance himself from Emperor Yuan of Jin and his line) but some sources indicate that he changed era name to "Yongle" (永樂 yǒng lè 346–353). A current theory is that his era name was used internally while the "Jianxing" era name was used when communicating with other states. After Zhang's death, Zhang Zuo became regent, and in early 354 usurped the title from Zhang Yaoling.
