Carrying a basket, forgetting to pick leaves, I dreamed of Yu Yang last night.

It turned out that she missed her husband who joined the army and was sad and resentful. The poem has hit the nail on the head, but it didn't directly say that the young woman missed her husband, but put it off until last night and said, "I dreamed of fishing for Yang last night." Writing is not only more graceful, but also can see the meaning of thinking day and night, all the time or already thinking, which is more profound than just writing the immediate thoughts.
