Su Shi is a representative of bold poets, and his poetic thoughts are open. How does the word "Shuidiao Tou" reflect this feature?

In the last two sentences, the author expressed his attitude towards human joys and sorrows with wishes: "May people live for a long time, but thousands of miles away." And the last "* * * ChanJuan" just shows that after the author was freed from suffering, the original feeling of complaining about others was put aside, but he hoped that those who left would be healthy for a long time and enjoy the moon together in a different place. It can be seen that the author still holds an open-minded and optimistic attitude towards the departure of life.
