Trivia, insights & behind the scenes
The title 樊笼 (fán lóng) literally means 'cage'—a classical metaphor for societal traps, but here weaponized as the tower itself and the mentor-disciple bond.
Fu Jing's casting as Zhuang Wujiu (note: different character name than Wujiao in synopsis—probably a typo fix) subverts her idol image; the role demands maternal warmth masking absolute ruthlessness.
