Zhang Juyong (張居詠), formally Duke Yi of Qinghe (清河懿公), was a chancellor of the Chinese Five Dynasties and Ten Kingdoms Period state Southern Tang and possibly its predecessor state Wu.
Zhang Juyong's birth date and geographic origin have been lost to history, as has his early career.
[2] In 939, Zhang Juyong was apparently among a group of officials who formally proposed that Xu Zhigao assume his birth family name of Li.
It was said that Zhang Juyong was graceful, silent, and moderate, and that, as chancellor, he expressed few of his opinions.
In 944, Li Jing removed Zhang from his chancellor position and made him the military governor (Jiedushi) of Zhenhai Circuit (鎮海, headquartered in modern Zhenjiang, Jiangsu).
