Their love story was not recorded in official historical annals, but was mentioned in the New Record of the Two Capitals (兩京新記, Liangjing xinji) written by Wei Shu (韋述)[1] and Poetry Stories (本事诗) by Meng Qi (孟啟).

The Sui Emperor then awarded the Princess to the State Duke of Yue, Yang Su, as a concubine.
