How does Wulingchun describe the author's feelings?

In Wulingchun, the author uses two external behaviors, namely "combing her hair wearily at night" and "crying first", to show her deep sadness. The sadness was so strong that she couldn't even mention it or touch it. "I heard that Shuangxi Spring is still good, and it is also planned to go boating." I heard that Shuangxi Spring is not bad, and the poet once had the idea of going boating there. She wants to go boating in Shuangxi, not because she craves beautiful scenery and enjoys swimming, but because she wants to find a way to eliminate her sorrow. However, instead, he denied his plan. "I'm afraid that the boat in Shuangxi can't carry many sorrows." I'm afraid that the boat in Shuangxi can't carry the heavy sorrow in my heart. Sorrow is invisible and intangible, but the poet compares it to a tangible entity, saying that he is so sad that he can't even carry a boat.
