"Eight Immortals Crossing the Sea" refers to a legend in Chinese mythology. In the legend, eight immortals each brought their own treasures and spiritual artifacts to the East China Sea to seek immortality. On the way, they encountered various difficulties and dangers, but they always helped each other overcome these difficulties. Eventually, they found the way to immortality and shared the secret together. However, the authenticity of this story had not been confirmed in history. It might just be a fictional legend used to express people's desire to pursue immortality and the courage to explore the unknown world. Therefore, it was no longer important whether the eight immortals in the Eight Immortals Crossing the Sea really existed. It was just a symbolic symbol and image.
