In order to pursue the noble and immortal soul of a person， the sea Princess Mermaid abandons the free life of the seabed and the life of 300 years， abandons the beautiful singing voice in the hands of the wicked witch， and endures the great pain caused by turning the fish tail into human leg.
With her love， her heart and her young life， to pursue the soul of the eternal and noble people， and through "good work" to share all the eternal happiness of people. The writer eulogizes the mermaid's pursuit of love， soul and ideal， and shows her good and pure character， strong perseverance and sacrifice spirit.
