Ah Chi is the younger sister of Ah Chu. Like her sister Ah Chi was sold off at an early age by her mother, Yin Sing Juk, to hide her shame. Unlike Ah Chu, who grew up as a servant in a well-educated and noble household, Ah Chi grew up amongst a clan of evil kung fu experts who use poison. Their master, Ding Chun Chow, raised and treated Ah Chi well. Because of this Ah Chi developed a disrespect for the lives of others, man and animal alike. Therefore Ah Chi had total opposite personalities to Ah Chu. The only similarity between them is that they like to play around, which is a characteristic of their mother. Ah Chu likes to dress up as other people, while Ah Chi likes to tease and torture others. Ah Chi and Ah Chu represent different extremes of which a child can grow up without being raised by their natural parents.

Mok Yin Ching had always thought that she was an orphan, who was raised up by her master at an early age. Her master made her wear a veil, which was only to be revealed to her future husband. If not Mok Yin Ching, would kill whoever remove her veil. Her master had a strong distrust for men so made Mok Yin Ching wear the veil. Along the way Mok Yin Ching fell in love with Din Yee, and in a desperate attempt to avoid having Master Lam of the 4 Big Bad guys remove her veil, removed it for Din Yee. Upon doing this she made Din Yee swear to marry her and love her only, otherwise it would be in her rights to kill. Din Yee accepted Mok Yin Ching terms.

As fate would have it they turn out to be half brothers and sisters of each other. Or so they thought. Thus preventing their marriage. It would also be revealed that Mok Yin Ching's master is actually her mother, Chun Hung Ming. Mok Yin Ching has the characteristics of her mother, aggressive and very direct. She is also a strong warrior. Just like her mother, Mok Yin Ching, loved Din Yee deeply, and could not forget him despite knowing that he was her brother.

Jong Ming is the last of Din Jing Sit's illegitament daughters. Her mother was Cheung Ka Bo. Upon realizing that she was pregnant, Cheung Ka Bo, married Jong Man Sau to hide her shame. Jong Ming fell in love with Din Yee when they first met along their journey. However when she discovered that Din Yee was her brother, she reacted well, and accepted Din Yee as her brother. Unlike the other girls, Wong Yee Yin, and Mok Yin Ching, Jong Ming's parents did not place a strong emphasis on a distrust of men. Therefore her love for Din Yee was not an all or nothing situation like that of Mok Yin Ching.

Din Jing Sit is the lord of Dai Li. A noble and flirtatious gentleman, who loves more than one woman. He had affairs with, Ah Lo (Misses Wong), Cheung Ka Bo (Misses Jong), Misses Mar, Chun Hung Min, and Yin Sing Juk. He was married to Do Bak Fung. Din Jing Sit's affairs for the crux of the events that occurred in the story. Infact Din Jing Sit's affairs affected nearly all of the characters in the story. Misses Mar felt greatly betrayed by Din Jing Sit, who promised her fame and fortune. Because of this she strangled the son that she had with Din Jing Sit and married Master Mar the VP of Coy Bong. This forms the basis of the trouble at Coy Bong.

Din Yee was affected by his farther's past on more than one occasion, for example discovering that Mok Yin Ching, Jong Ming, and Wong Yee Yin were his sisters. Luckily Din Jing Sit's affairs, angered his wife Do Bak Fung, who wanted to do some to get him back. She decided to have Din Yin Hing's child who was Din Yee. Ah Chi and Ah Chu became orphans because of Din Jing Sit.

Despite this Din Jing Sit is a very wise and honorable man. Once all of his woman are killed by Mo Yung Fok, Din Jing Sit, finds no purpose for living and decides to commit suicide. Therefore although Din Jing Sit does not love any one particular woman, his love for them is true and equal.

Misses Mar is a selfish cold hearted woman. She uses her beauty to gain power. Since she was little, she had always wanted fame and fortune and would use any means to get it. What she wants she gets otherwise she would destroy it rather than have someone else have it. Thus she sought to kill Din Jing Sit, one man whom she had once loved. Din Jing Sit promised her fame and fortune, and when she did not obtain it from him she killed her own son and married someone else.

She married Master Mar of Coy Bong, a man she did not love, because he posses the title, VP of Coy Bong, and was the next to become their leader. She flirted with Kiu Fung, because she wanted to be the wife of the leader of Coy Bong. When Kiu Fung rejected her she felt betrayed once more and plotted his downfall. Regardless of whether Kiu Fung, was a good leader or not, Misses Mar was set on becoming the wife of the Coy Bong leader. Therefore she attempted to persuade Master Mar, to plot against Kiu Fung. When he refused Misses Mar felt betrayed and used her beauty to gain the help of Master Bak, and Chin Koon Ching to kill Master Mar.

Yau Tan Ji is the son of Master Yau of Ju Yin Jong, who held a kung fu forum in an attempt to deal with Kiu Fung. His parents used dirty tactics and was defeated by Kiu Fung. To hide their shame they decided to kill themselves. Despite this Yau Tan Ji blamed Kiu Fung for killing his parents.

Yau Tan Ji is similar to Din Yee, in that he follows Ah Chi around and would do anything for her. He risks his own life to help Ah Chi, complete her poison kung fu. He also presents Ah Chi with his own eyes so that she could be cured of her blindness. Yau Tan Ji, also admitted Ding Chun Chow as his master in order to save Ah Chi. Despite all of this Yau Tan Ji's love is unrequited. Ah Chi never treats Yau Tan Ji well.

Therefore unlike Din Yee another dog, who followed Wong Yee Yin around, Yau Tan Ji never ends up with Ah Chi. This goes to show that not all unrequited lovers are rewarded. Wong Yee Yin is a kind-hearted person so Din Yee was lucky. Ah Chi is a heartless person so Yau Tan Ji was unlucky.
