Forget it, I'll give you the answer!
The question and answer between subject and object is only a form of expression of Fu, which actually reflects Su Shi's own thoughts. Here, we can see the deep depression of an idealistic and ambitious intellectual in feudal times after being hit politically, and his ideological contradiction and its development and change process in trying to get rid of this mental depression. Through the description of natural beauty and the creation of poetic artistic conception, the author truly and vividly reveals his complex spiritual world and expresses his deep thinking about life. On the surface, he is aloof, broad-minded and optimistic, but after careful understanding, we can find that the author's heart is still full of contradictions and depression. His idea of enjoying his life and pinning it on nature is just a kind of helpless self-comfort, which is itself a manifestation of inner depression, which is not exactly the same as our optimism with confidence and hope for life and the future today. His view of change and invariance is not absolute, which is not without merit, but it is also different from what we call dialectics, but the expression of Lao Zi and Zhuang Zi's subjective idealism relativism philosophy, which obliterates the difference between things and me. Nevertheless, after suffering a cruel political blow, he was in adversity without being negative and decadent, and showed an open-minded, cheerful and detached spirit, which was also commendable under the historical conditions at that time. Enthusiastic praise for mountains and rivers, admiration for heroes in history and pursuit of ideals all reveal the author's love for life, which is worthy of recognition. We are infected by reading.
