Prince Yide's tomb and Princess Yongtai's tomb are also one of the seventeen burials in Ganling. Although they are accompanying tombs, the historical biography of Prince Yide and Princess Yongtai also died young because of Wu Zetian. From the murals of the underground graveway, it can be seen that Li Xian of the middle Tang Dynasty was helpless for the death of Prince Yide, the eldest son.

The tomb owner's prominent position and special status, as well as the story of ghost marriage, make people feel the pity of the imperial family, can only be buried with the coffin.
