These two sentences use exaggerated rhetoric to describe different landscape pictures: the lotus leaf and the blue sky, which extend to the end of the lake, blend together to create an "infinite" artistic space and draw endless blue; On this blue background, the lotus reflected by the sun is lit, so beautiful and bright. "Infinitely blue" lotus leaves in the sky and lotus flowers reflecting "different colors of red" in the sun can be seen not only in spring, autumn and winter, but also in the most vigorous summer of mid-June. The poet captured the unique scenery of this midsummer and summed it up very aptly.
