Shen Zhenzhu's ending is both clear and mysterious. It is clear that Shen Zhenzhu is the mother of Tang Dezong Shili, and she was named Queen Ruizhen. The emperor's mother, her birth and important experiences are recorded in Historical Records. This is a mystery, because since the birth of Li Yu (), the Tang Dynasty is experiencing the biggest turmoil-An Shi Rebellion. Shen Zhenzhu, on the other hand, disappeared in the late Anshi Rebellion.
In the 15th year of Tianbao (756), after the Anshi Rebellion, Chang 'an was advanced, and Emperor Xuanzong of Tang Dynasty fled hastily with his grandchildren, including Yang Guifei and Li Yu, and Shi Li, while the concubines and a large group of royal families of the emperor's grandson were left behind, captured by the rebels, and looted from Chang 'an in Xijing to Luoyang in the east, including Shen Shi.
Tang Suzong Hengli proclaimed himself emperor in Lingwu, and named his eldest son, Li Yu, the marshal of the military forces in the world. In 757, Li Yu recovered Luoyang, the eastern capital, and found Shen Shi who had been imprisoned for more than a year in Ye Ting. In 758, Li Yu was established as the Crown Prince, but Shen Shi's birthright was not clear, and he was not welcomed back to Chang 'an. Instead, he lived in Luoyang Palace. In 759, Shi Siming captured Luoyang again, and Shenshi disappeared.
Shen Zhenzhu's son Shi Li died after 26 years in office. His eldest son acceded to the throne in Shunzong and died after July. His eldest son Xian Zong acceded to the throne. At this point, the search for Shen Shi has been going on for decades and there is still no news. Some departments suggested that it should be stopped, and at the same time, a letter was sent to mourn for Shen Shi in Su Zhang Inner Hall, incense was given to Empress Dowager Tai, a cenotaph was built in Daizong Mausoleum, and a shrine was established in Daizong Temple.
