Juedai Shuangjiao

• Xiaoyu'er (小魚兒; Xiǎoyúér; 'Little Fish'), born Jiang Xiaoyu (江小魚; Jiāng Xiǎoyú), is Jiang Feng and Hua Yuenu's son. He was raised by five of the Ten Great Villains and trained to become a great villain. Though his body is covered in scars due to his brutal upbringing, he possesses considerable charm and rugged good looks, which allow him to leave a lasting impression on every woman he meets. Although a respectable fighter, Xiaoyuer prefers to rely on his intelligence, cunning, and a variety of skills such as thievery and deception to overcome challenges. However, when he encounters Hua Wuque, he realises that he cannot rely on tricks alone to stay alive, so he starts honing his fighting skills and ultimately turns into a formidable martial artist in his own right. Although his tough upbringing causes him to adopt a callous, hedonistic persona in public, he has a strong moral compass and is naturally kind and protective of others.
• Hua Wuque (花無缺; Huā Wúquē) is Xiaoyuer's fraternal twin brother, and the heir to Yihua Palace and its only male resident. Bearing a striking resemblance to his father, he looks extraordinarily handsome and has a more androgynous appearance compared to his brother. He is highly respected in the jianghu for his formidable prowess in martial arts and his gentlemanly, graceful manners. However, he has a tendency to suppress his emotions and has a naive outlook towards life.
• Tie Xinlan (鐵心蘭; Tiě Xīnlán) is Tie Zhan's daughter. Although she has a beautiful appearance and seems soft-hearted, she is actually strong-willed, brash and extremely stubborn. A decently good fighter, she has been trained by her father to use the "Berserk Hundred Hits" (瘋狂一百零捌打). She falls madly in love with Xiaoyuer even though he initially treats her badly. She later falls in love with Hua Wuque, who has strong feelings for her. This results in her becoming entangled in a love triangle between the brothers, and she often has to intervene to prevent them from fighting.
• Su Ying (蘇櫻; Sū Yīng) is Wei Wuya's foster daughter. Spoiled, arrogant, scheming and anti-social, she is well-versed in medicine and extremely cunning but quite mediocre in martial arts. Her intelligence enables her to manipulate many martial artists, while her beautiful appearance and indifferent personality are similar to those of Yaoyue and Lianxing – which was why Wei Wuya adopted her. When she meets Xiaoyuer, she falls in love with him and decides to follow him until she wins his heart. She is more intelligent than him and knows how to bend him to her will.
• Yan Nantian (燕南天; Yàn Nántiān), nicknamed "Best Divine Swordsman Under Heaven" (天下第一神劍), is Jiang Feng's sworn brother and one of the most powerful martial artists in the novel. His prowess in swordplay is unmatched in the jianghu and his "swordsman aura" can be even felt from a distance. Massive in stature and dressed like a pauper, he is so powerful that he can shave a man bald in a single sword movement without the man noticing it. After he is ambushed and knocked unconscious by the Ten Great Villains, he is revived by Wan Chunliu, who kept him alive under the pretext of using his comatose body to test new drugs. When he regains consciousness, he realises that he has lost his prowess in martial arts, so he trains for many months to regain his powers and eventually surpasses his original self. He serves as Xiaoyuer's role model and trains him in martial arts.
• Lu Zhongyuan (路仲遠; Lù Zhòngyuǎn), nicknamed "Great Hero of the Southern Sky" (南天大俠), is Yan Nantian's close friend and one of the most powerful martial artists in the novel. In his prime, he had defeated Du Sha before but had lost to Wei Wuya and had disappeared from the jianghu for several years before reemerging. He dies after falling into a trap set by Jiang Yulang.
• Jiang Feng (江楓; Jiāng Fēng), nicknamed "Yulang" (玉郎; 'Jade Young Man') was Xiaoyuer and Hua Wuque's father. He met Hua Yuenu of Yihua Palace, fell in love with her and eventually eloped with her. He committed suicide to join his wife after she was killed.

• Yao Yue (邀月; Yāoyuè) is the first mistress of Yihua Palace and a formidable martial artist. Although she possesses beauty, charisma and skill, she is described by Jiang Feng as "not a living person or human being, but fire, a block, ice or a sword instead". Jiang Feng rejects her and elopes with Hua Yuenu. Angered, Yaoyue pursues and hunts down the couple. After Jiang Feng and Hua Yuenu die, Yaoyue intends to kill their twin boys but Lianxing stops her. The sisters choose one of the twins and raise him as their son and groom him to be the heir to Yihua Palace.
• Lian Xing (憐星; Liánxīng) is the second mistress of Yihua Palace and Yaoyue's younger sister. She is described to be a sweet and pretty woman whose beauty surpasses that of a flower blooming in spring. According to Xiaoyue'er, in comparison to Yaoyue, Lianxing is warmer in character than her sister. This is confirmed by Tie Pinggu, because Lianxing, like Yaoyue, had also fallen in love with Jiang Feng, but was afraid to express her feelings for fear of her sister. After Jiang Feng and Hua Yuenu die, Lianxing saves the twins by suggesting to make them kill each other when they are grown up instead of killing them now. Throughout the novel, it is hinted that Lianxing, unlike Yaoyue, does not take the revenge plot seriously. Hua Wuque sees Lianxing as a mother-figure and treats her with love and respect. Compared with Yaoyue and Yan Nantian, Lianxing is slightly weaker in martial arts than her sister, but equal to Yan Nantian.
• Hua Yuenu (花月奴; Huā Yuènú) was a servant of Yihua Palace. She met Jiang Feng by chance, fell in love with him, and eventually eloped with him. She was killed shortly after giving birth to Xiaoyuer and Hua Wuque.
• Tie Pinggu (鐵萍姑; Tiě Pínggū) is a servant of Yihua Palace who helps Xiaoyuer escape from Yaoyue. She is deceived by Jiang Yulang and loses her virginity to him, and is used as bait to lure Xiaoyuer into a trap. After she is abandoned by Jiang Yulang, she feels dejected and chooses to join Hu Yaoshi and the Twelve Zodiac. She is ultimately revealed to be Li Dazhui's daughter from .
• He Lu (荷露; Hé Lù) is a servant of Yihua Palace.
