Trivia / The Princess Wei Young

• Dawson Casting:
  • Vanness Wu (Tuoba Yu) is ten years older than Mao Xiao Tong (Chang Ru), but their characters were childhood friends. Made even stranger when flashbacks to their childhood show Tuoba Yu and Chang Ru are the same age, while as adults they clearly aren't.
  • Luo Jin (born 1981) plays the grandson of Canti Lau (born 1964).
• "Do It Yourself" Theme Tune:
  • Tiffany Tang and Luo Jin sang "天赋/Tiān Fù/Heavenly Gift".
  • Jin Han (Chiyun Nan) sang "緣因我/Yuán Yīn Wǒ/Fate Because of Me".
• Romance on the Set: Tiffany Tang (Xin Er) and Luo Jin (Tuoba Jun) began dating in real life and got married in 2018.
• Time-Shifted Actor:
  • Li Yi Xiao plays the real Wei Young as an adult and Zhao Shu Ting plays her as a child.
  • Vanness Wu plays Tuoba Yu as an adult, Huang Tian Qi plays him as a child and Huang Hai Ge plays him as a baby.
• Underage Casting: In addition to the seventeen-year age gap between grandfather and grandson, Canti Lau (Tuoba Tao) is only fourteen years older than Vanness Wu.
