Shuangpo Shuangniang of Yanhui Peak met Xie Heng, a young man guarding the border, in the plum snow. They made tea in the snow and made a promise to stay together with plum branches and jade pendants. When the war breaks out, Xie Heng resolutely goes to the army. His soul is broken in Yanmen, leaving only half of the jade pendant to hide the unfulfilled promise. With the thousand-year spiritual energy as her obsession, Frost Lady guarded her solitary grave for three hundred years, watching the Manzhushahua flowers bloom without leaves and leaves without flowers. Eventually, when the spiritual energy was exhausted, it turned into frost particles and merged into the tomb soil. Flowers and leaves take different paths, separated by life and death, a tender encounter eventually becomes an unsolvable regret that spans three hundred years.
