Jiuquanzi · Long memories of tide watching

Northern Song Dynasty——Pan Lang

I often think of the time when I watched the tide in the past,

People all over the city rushed to see the scenery on the river.

When I think about it now, I always suspect that it was all an illusion.

I felt like I was surrounded by the noise of ten thousand drums.

(Thinking back to that time) The tide-dweller stood facing the peak of the tide.

The red flag he held in his hand was not wet by the tide.

Now that I have said goodbye to this situation, I can only recall it over and over again in my dreams.

I still feel miserable when I wake up from the dream.
