Fan Xian had learned Sigu Jian's swordsmanship and martial arts because Sigu Jian had imparted them to Fan Xian. In the novel " Joy of Life," Sigu Jian was the Lord of Dongyi. He was Fan Xian's brother. After Fan Xian discovered that the Eldest Princess had sold Yan Bingyun's information to Northern Qi during his night visit to the Royal Palace, in order to clear his name of responsibility, he framed Sigu Jian and had Wu Zhu imitate his writing style. Fan Xian believed that because Sigu Jian had killed his entire family, he could do anything. But in reality, Sigu Jian was not a cold and heartless person. His upbringing had shaped his character. As the illegitimate son of the City Lord of Dongyi and a servant girl, his status was low and he did not have the support of his mother's clan. Moreover, his mother had passed away very early, which made his situation even more difficult. He was born with low intelligence. He was already in his teens, and he only knew how to squat in front of the city lord's mansion and look at ants. His father and stepmother despised him. These experiences had caused Sigu Jian to be bullied and neglected from a young age, forming a solitary and cold personality. Even though Sigu Jian's appearance was cold and heartless, deep in his heart, there was an unknown tenderness and warmth. When he faced his family, friends, and loved ones, he showed firm protection and care. Thus, Sigu Jian imparted his swordsmanship and martial arts to Fan Xian, hoping that he would receive protection and help.
