This sentence came from the Tang Dynasty poet Wang Zhihuan's poem "Climbing the Stork Tower". The white sun is leaning against the mountains, and the Yellow River flows into the sea current. I want to see a thousand miles and climb another level. The boy posted on his WeChat Moments that the south wind knew what he meant and dreamed of Xizhou. It could be understood that what he wanted to express was that the north wind knew what he meant and dreamed of Xizhou. The image of this sentence was that the North Wind and the West Province represented the feelings and dreams that boys wanted to pursue. The south wind symbolized a vague and ambiguous emotion that might not be completely realistic and a clear goal. Therefore, the boy used the phrase " the south wind knows my intentions " to express his hazy thoughts about his feelings and dreams.
