They seek simplicity. For example, you can't see or touch "mother's love," but you can write: "Mother's love is a full bathtub of water / I lie in it and fall asleep." Warmth and peace are represented by the feeling of falling asleep in the bath--that's poetry.
例如「媽媽的愛」雖然摸不到、看不到，但他會寫：「媽媽的愛是一盆滿滿的洗澡水／我躺在裡面睡著了」──可以躺在裡面睡著，那種安心、溫暖就表現出來了。
