Lan Xichen

Lan Xichen is a tall, slender man with delicate features. He closely resembles his younger brother, but there are two key differences: Lan Xichen's eyes are softer and darker. His facial expression is almost always smiling, while Lan Wangji maintains a calm demeanor. Thanks to his appearance, Lan Xichen has been recognized as the most handsome young master in the cultivation world of his generation. He wears the white robes of the Gusu Lan Sect and a ribbon embroidered with clouds on his forehead. His spiritual weapons, the Liebing Flute and the Shuoyue Sword, hang from his waist. Lan Xichen has a kind and gentle nature. He is polite to everyone he meets and treats everyone equally, regardless of social status. He tends to believe the best in people and often tries to understand their motives, even if they are disappointed. He is slow to anger and only loses his temper when those he loves are offended. For example, he becomes enraged when he thinks Wei Wuxian might have deliberately mocked Lan Wangji's feelings. Lan Xichen also shows deep concern for his younger brother and seems to be the only one capable of reading his emotions from his usually impassive face. He is bound by an oath of sworn brotherhood with Nie Mingjue and Jin Guangyao. Thus, Lan Xichen is the embodiment of gentleness, kindness, and principled politeness, while remaining steadfast in protecting those he holds dear.

Lan Xichen (real name: Lan Huan). He is the eldest son of Qingheng-Jun (the former head of the Gusu Lan Sect) and Madam Lan, nephew of Lan Qiren (the sect's elder), and older brother of Lan Wangji. Together, the brothers are known as the "Two Jades of the Lan Clan." Title: Zewu-Jun - "Lord of the Blessed Wilderness." Weapons: Sword Shuoyue ("New Moon") and Flute Liebing ("Icebreaker"). Height: 188 cm. From an early age, Lan Xichen was under the tutelage of his uncle, Lan Qiren, who practically single-handedly ruled the sect while his brother, Qingheng-Jun, remained in seclusion. Lan Qiren raised his nephews with strictness, trying to protect them from their parents' mistakes. Lan Xichen's mother, Li Yunzhu, committed murder and then suicide when the brothers were still children. Lan Xichen deeply mourned her death. Lan Xichen participated in the Sun Annihilation Campaign, a war against the Qishan Wen Sect. During his travels, he met Meng Yao, who provided him with support and shelter, which later led to a close friendship and a so-called brotherhood. After his father's retirement, Lan Xichen became the head of the Gusu Lan Sect. He proved himself a calm and diplomatic leader, less inclined to radical decisions and violence. His anger only manifests when it affects those he loves—for example, when he learns that Wei Wuxian may have deliberately mocked Lan Wangji's feelings. Relationships with other characters:
