Literature Reference: 独鹤声哀羽摧折，沙头一点留残雪。三山侣伴能远翔，五里裴回忍为别。惊群各畏野人机，谁肯相将霞水飞。不及川凫长比翼，随波双泛复双归。碧海沧江深且广，目尽天倪安得往。云山隔路不隔心，宛颈和鸣长在想。何时白雾卷青天，接影追飞太液前。—— 《病鹤篇》 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'.
