In 667, Yang was given the designation of Tong Dong Xi Tai Sanpin (同東西臺三品), making him a chancellor de facto. It was said that Yang Hongwu was not talented as a chancellor, but was known for being humble and careful, as well as being simple in his actions. He died in summer 668 and was buried with honor, with the posthumous name of Gong (恭, "respectful").
