Bird Image in China's Classical Poetry: Free Soul.
Su Zhe (Ziyou)' s original poem has the words "Farewell to Jacky, and be afraid of snow and mud when traveling far away". Su Shi's harmony poems are triggered by "snow mud", which turns reality into nothingness and creates a famous metaphor of "snow mud with claws", which refers to the traces left in people's hearts in the past. The finger marks on the snow mud are still there, just like the memory in the poet's heart, but the bird has already flown to nowhere, and the poet brothers who have preserved the memories of the past have also gone through hardships. Su Shi walked through the snow with a flying rainbow and disappeared without a trace, suggesting the accident and uncertainty of life. His image is beautiful and vivid, and his philosophy is profound, which makes people realize and feel disappointed.
