Tracing back to the Book of Songs, the original sentence is: swim from its own source, and everything is in the middle of the water. It's too long to go upstream to find her. The antonym of tracing is tracing, and tracing refers to going downstream.
Full version of the original poem:
The Millennium is frost. The so-called Iraqis are on the water side. Tracing back and forth, the road is blocked and long. Swim back from it, in the middle of the water

Translation:
The river is green with reeds and frost in autumn. Where is the right person? Just across the river. It's too long to go upstream to find her. Follow the running water to find her, as if in the middle of the water. The reeds by the river are dense, and the morning dew is not dry. Where is the right person? Just beyond the river bank. Sail against the current, it is hard to go climbs.
Follow the running water to find her as if she were in a state of water. The reeds by the river are thick and thick, and the dew has not been completely collected in the morning. Where is the right person? It's just beyond the water. It's hard to find a way to find her against the current. Follow the running water to find her, as if on a beach.
