Jin Zixuan wears the yellow robes of the Lanling Jin Sect. He has his black hair pulled up in a ponytail.
Jin Zixuan is arrogant, having no issue with insulting Jiang Yanli while her brothers were in range to hear. However he was also willing to stand up to Wen Chao when the latter ordered them to seize Mianmian to be sacrificed in order to lure a monster, protecting her alongside Wangji even though he knew his actions would have consequences.
Jin Zixuan and Jiang Yanli were in an arranged marriage. Originally the two had no interest in each other, though the two did eventually fall in love and have a child.
Jin Zixuan is Jin Ling's father. He was protective of Jin Ling when he was alive.
Jin Zixuan and Wei Wuxian did not get along. Their dislike of each other increased when Wei Wuxian started a fight between them after Jin Zixuan insulted Jiang Yanli of being an average girl, unsuitable for his status. This did not diminish after Jin Zixuan and Jiang Yanli got married, but both respected each other for being Jiang Yanli's beloved person. After Wei Wuxian became the Yiling Patriarch, Jin Zixun attempted to attack him when Wei Wuxian was travelling to Jin Ling's birthday where he was invited by Jin Zixuan. Jin Zixuan who caught up of the secret ambush to his guest, tried to stop the fight but the encounter ended in Jin Zixuan's death by the hands of Wen Ning.
