The following is a list of characters from the wuxia novel A Deadly Secret by Jin Yong.
Luohua Liushui
The "Luohua Liushui" (落花流水; luòhuā liúshuǐ; 'falling petals and flowing water') is a group of four martial artists from orthodox schools. They track down Grandmaster Xuedao and Di Yun to Tibet to rescue Shui Sheng, who has been taken hostage by Xuedao.
- Lu Tianshu (陸天抒; Lù Tiānshū) is the oldest in the group. He is killed by Xuedao while trapped in the snow. His corpse is later eaten by Hua Tiegan.
- Hua Tiegan (花鐵杆; Huā Tiěgān) is the most scheming and treacherous of the four. He reveals his true colours after Xuedao is killed by Di Yun. He resorts to cannibalism and sustains himself by eating the flesh of his fallen companions. After escaping from the snowy valley, he falsely accuses Shui Sheng and Di Yun of sexual immorality in front of Shui's fiancé, causing them to be separated. He becomes insane after coming into contact with the cursed jewels.
- Liu Chengfeng (劉乘風; Líu Chéngfēng) is killed by Hua Tiegan unintentionally during a duel with Xuedao. His corpse is later eaten by Hua.
- Shui Dai (水岱; Shuǐ Dài) is Shui Sheng's father. He is mortally wounded in a fight against Xuedao, and he begs Di Yun to perform a coup de grâce on him to end his suffering, which Di reluctantly did.
