son's death, he had Su Wen burned alive, Jiang Chong's immediate and extended family executed, and killed every official promoted for tracking down the Crown Prince. He also promoted Tian Qianqiu to prime minister, and made major policy change rectifying the ideals supported by his dead son. To express his regret over causing his son's death, Emperor Wu also built the Palace of Son-Grieving (思子宮) and Platform of Longing for Return (歸來望思台), officially rehabilitating Liu Ju's name. 18 years after her death, her great-grandson Liu Bingyi ascended to the throne in 74 BC as Emperor Xuan. Emperor Xuan then had his great-grandmother's name officially cleared and rebuilt her tomb to a larger mausoleum cared by 1000 men, and gave her the posthumous title Wei Si Hou (衛思后, literally meaning "Wei the Thoughtful Empress"). Her new tomb, due to its remote location and relative humbleness, escaped the looting by tomb raiders later.
