宋璟
Su Ting (蘇頲; 680 – July 31, 737), courtesy name Tingshuo (廷碩), formally Duke Wenxian of Xu (許文憲公), was an official of the Chinese dynasty Tang Dynasty and Wu Zetian's Zhou Dynasty, serving as a chancellor during the reign of Emperor Xuanzong. He was a capable supporting chancellor to Song Jing, and he was also immensely gifted literarily, ranking with Zhang Yue as the two great literary figures of their time. They were known in unison as 燕许大手笔 ("Immense pen-brushes from Yan and Xu").
