Gu Chengxiang Pingchangsheng was a native of an unknown place. He died several times and then came back to life, but people at the time did not believe it. Later a great flood occurred, and many were harmed by it. Ping would then shout from the top of Quemen Mountain: "Pingchangsheng is here!" He said that after five days, the rain and floodwaters would cease. When they stopped, people went up the mountain to seek a shrine for him, but saw only Ping's robe, sash, and leather belt. Several decades later, he became again a gate guard in Huayin.

Like Laozi, who transcended ordinary existence and left behind only traces of his passing, Pingchangsheng embodied the Taoist ideal of the immortal who moves between life and death without attachment. His ability to command the floodwaters recalls the ancient Taoist reverence for water as the supreme force of nature — yielding yet irresistible.

The Yellow Emperor is said to have sought immortality through cultivation and inner alchemy; Pingchangsheng achieved a similar transcendence not through grand ritual, but through humble, repeated return — dying and living again as naturally as the seasons turn.

His final reappearance as a gate guard in Huayin echoes the story of Jie Zitui, another immortal who chose obscurity over recognition, vanishing into the mountains rather than accepting worldly reward.

Gu Cheng Miao Pi was eccentric and extraordinary. He went from life to death, his nature never constant. His mystical transformation transcended form; he cared not for status or wealth. Temporarily descending into worldly filth, in the end he soared to the clouds.

This eulogy places Pingchangsheng among the great wandering immortals of the Lie Xian Zhuan. Compare the longevity cultivation of Peng Zu, who sustained his vitality through breath and diet over centuries, or the cosmic mastery of Rongcheng Gong, who absorbed the essence of heaven and earth — Pingchangsheng's power lay not in technique but in his indifference to the boundary between life and death itself.
