Why are the lines of Bing Xin's poems not aligned?

Some are to emphasize certain contents. If you align blindly, you can't highlight what the author wants to emphasize. For example, some question-and-answer poems can be staggered. Things are different. Ancient poetry pays attention to parallelism, neat antithesis, rhythm and artistic conception, just like classical Chinese. Modern poetry uses vernacular, pays more attention to emotion and meaning, and has low requirements on format and rhythm.
