Kou Xian was a native of Song. He made his living by fishing, and lived near the Sui Shui for more than one hundred years. When he caught fish, he would sometimes release them, sometimes sell them, or sometimes eat them himself. He often wore a hat and sash, loved to plant lychees, and enjoyed eating their flowers and fruits. Song Jinggong asked him about his methods, but when he did not reveal them, Song Jinggong had him killed. For several decades, he occupied the gate of Song city, playing the guqin for dozens of days before leaving. Families in Song all honored and worshipped him.

Kou Xian’s refusal to share his Dao with the king — even at the cost of his life — is a defining Taoist act. As Laozi taught, the Dao that can be spoken is not the eternal Dao; it cannot be demanded or extracted by power. The king’s violence only confirmed his ignorance, while Kou Xian’s return from death confirmed his mastery.

His use of the guqin as a final act of presence connects him directly to Qin Gao, another immortal musician of the Lie Xian Zhuan who played the zither as a bridge between the mortal world and the realm of the divine. Both figures used music not as performance, but as a form of spiritual transmission.

Like Fan Li, who abandoned vast wealth and power to live freely with the Dao, Kou Xian chose the simplicity of fishing and lychees over the court — embodying the principle of wu wei, acting without striving, living without grasping.

Kou Xian cherished the Dao, and his techniques were not falsely transmitted. Jinggong killed him, but he attained transcendence through spiritual transformation after death. After fifty years, he returned by playing the zither. He waited at the gate of Song, freely expressing his feelings through the five strings.

The concept of shijie — transcendence through apparent death — is one of the most distinctive ideas in Taoist immortality lore. Kou Xian’s body was destroyed, yet his spirit endured and returned. This mirrors the teaching of Jie Zitui, whose disappearance into the mountains was similarly interpreted as a form of spiritual liberation rather than mere death. Both figures remind us that in the Taoist worldview, the boundary between life and death is not a wall but a threshold.
