What are the meanings of these poems about bamboo written by Su Shi?

Su Dongpo's love for bamboo is perhaps unprecedented. Bamboo will accompany him all his life. Wherever he goes, he can't live without bamboo. "Better eat without meat than eat without bamboo" is his famous saying. When Dongpo was young, there was a heroic wind of singing bamboo: "there are ten thousand bamboo poles in front of the door and four books in the class"; Looking at bamboo in middle age, my mood tends to be dull: "The bamboo is sparse outside the curtain, and the rain is clear between the bamboos." The window sash is clean, and it is cold and foggy "; In old age: "When you are tired, you have nothing to say, and the wind blows the bamboo whistle", "Put on your clothes and sit in a small pavilion and make temporary bamboo". From heroic to calm, this is his life track, and the bamboo in the poem is a portrayal of his mentality in different periods. This is his own summary of his life, a feeling.
