Zheng Zhu
Song would never be allowed to return to Chang'an while alive, and he died in 833 while still serving as Kai Prefecture. Emperor Wenzong ordered that his body be allowed to be returned to Chang'an for burial. In 836 — after a plot that Emperor Wenzong had with Zheng Zhu (who had, by that point, turned against the eunuchs) and Li Xun to slaughter the eunuchs (known as the Ganlu Incident) failed, leading to Zheng's and Li Xun's deaths — Song's reputation and offices were posthumously restored, and he was given further posthumous honors. His son Song Shenwei () was made a county sheriff.
