From Su Shi's "Shuidiao Getou" in the Song Dynasty, the word Zizhan was named Dongpo Jushi. Su Shi's father's name is Su Xun, and his younger brother's name is Su Zhe. They are known as the "Three Sus" in the world, and both of them are listed among the "Eight Masters in Tang and Song Dynasties". "Chanjuan" is a beautiful appearance, here refers to Chang 'e, which means the moon. "Wish people a long life" is to break through the time limit; "A thousand miles together" is to break through the barriers of space.

The poet's two meanings are: I hope the person I miss will be safe and long-lasting. No matter how far apart the mountains are, we can all see the bright and beautiful moon together. This sentence is often used to express thoughts and blessings for distant relatives and friends. I only hope that the people I miss will live a long and healthy life, even if they are thousands of miles apart, they can share this beautiful moon.
