2. leaning: leaning and attaching. Listen to the wind and rain: listen to the wind and rain.
3. This is what is said in "Two Dreams of the Storm": "Listen to the wind and rain and overlook the rivers and lakes." The writer is Ma Rongcheng, a contemporary Hong Kong painter. The whole poem: Missing is a kind of pain, leaning against the building and listening to the wind and rain, regardless of the rivers and lakes. You can see the bright tears on her cheeks now, but you can't see the man she loves so much!
The main idea of the poem is that missing is a kind of pain. Listening to the wind and rain in the pavilion makes the Jianghu road indifferent. I only see tears on my cheeks, and I don't know who I love.
