"People have joys and sorrows, and the moon waxes and wanes." Every time I read this poem, I don't have Su Shi's open-minded feelings, but instead feel sad. No one can change the waxing and waning of the moon, but isn't it a kind of helplessness for people's joys and sorrows? There is no joy, there is endless sadness, separation and separation, separation, fate, and helplessness. Sometimes I think that "sadness and joy" are not just two opposites of "sadness" and "joy", "sadness and joy" can also be "sad joy". The coexistence of "sadness" and "joy", indescribable complexity and helplessness, is the unique emotion of human beings, like a hazy mist, inexplicable and impossible to find. From this, I wrote "Sorrows and Joys, Separation and Reunion" to interpret what "sorrows and joys" are and what "separation and reunion" are.
