This is a love affair that spans thousands of years. Su Yao is endowed with the gift of immortality. She walks alone in the torrent of time and suffers from loneliness. However, she treasures her first encounter with the border guard general Xiao Hanchuan and their tender love in her heart. From the wind and sand in the desert of the northwest, to the mist and rain in the water towns in the south of the Yangtze River, from the turmoil on the beach in Shanghai, to the prosperity of the ten miles of Xiangjiang, she repeatedly encountered the figure who carried Xiao Hanchuan's soul during her reincarnation. Every reunion is a continuation of love and courage. They were not afraid of secular prejudices, broke through the barriers of time and space, and faced the passage of time with their deep feelings, composing an immortal love song that spans mountains, seas and time.
