the head of the examination bureau, which by that point had been renamed Huangmen Sheng ()) and acting minister of civil service affairs. Emperor Xuanzong also created Song the Duke of Guangping. Song and Su worked well together, with Song taking the leading role and Su the assisting role. With Yao having distinguished himself as one who modified the regulations to fit the situation and Song known for following the laws strictly and fairly, it was said that while their styles were different, they were both considered great chancellors of Emperor Xuanzong's reign. Song was also known for often making suggestions to correct Emperor Xuanzong's and governmental officials' behavior, thus causing Emperor Xuanzong to respect him more.

He suggested that not only the monument be abolished, but that such actions be prohibited in the future, and Emperor Xuanzong agreed. When Emperor Xuanzong's father-in-law Wang Renjiao ()
