Tell me the meaning of the last two lines on the street.

Expressing his loneliness. The last two sentences of "On the Street" written by Zhang are that the sun climbs quietly from tiptoe to knee, and I also want to watch the black whirlwind water fight in the waves. The sun can't shine from the feet to the knees, and the black whirlwind water can't make white stripes in the waves, expressing its loneliness. In this poem, the poet used a series of anti-common sense language, which played a defamiliarization effect, from mailbox loneliness, digital loneliness, street loneliness to human loneliness, and achieved a defamiliarization effect.
