杨华的主要文学成就表现在诗歌创作上。他的小诗在极大程度上接受了冰心，在抒发对世界对人生恍惚不定的思绪时，更多地赞美生命、亲情、友情，微带着忧愁，又满贮着温柔，给人以持久的甜意和暖意，甚至诗句本身就是人生的哲理和智慧。他的《黑潮集》讴歌台湾人民的反抗斗争，控诉残酷的殖民统治，喊出殖民地人民的心声。其余诗歌也保持着永远的控诉，只不过用曲笔、用隐喻、用暗示来表现。 Yang Hua’s main literary achievements are reflected in his poetry. His poem, to a great extent, accepted Bing Xin’s words and expressed more praise for life, affection, friendship and slight sorrow when expressing his thoughts about the world’s trance. Sweetness and warmth, even the poem itself is the philosophy and wisdom of life. His “Kuroshio” sang the rebellious struggle of the people in Taiwan, accusing brutal colonial rule and shouting the voices of the colonial people. The rest of the poem also maintains a permanent complaint, only with the use of music pen, metaphor, with cues to performance.
