Literature Reference: The lone crane's mournful cry, its feathers broken by the frost, leaves a trace of residual snow on the sandy shore. Its companions from the three mountains can fly far, yet it lingers for miles, reluctant to part. Each fears the snares of the wild, who would dare to fly together through the misty waters? Not as fortunate as the river ducks that swim in pairs, riding the waves together and returning side by side. The vast and deep blue sea and the dark river stretch endlessly, where can one go to the end of the sky? Though mountains and clouds block the path, hearts remain connected, the longing for a harmonious song persists. When will the white mist clear the blue sky, allowing shadows to chase and fly to the front of the Taiye Pond. Source from 'Bing He Pian'.
