Bai Yun said: "There is an angel. At a certain moment, the butterfly's heart suddenly becomes brighter. It's like the sun shines into the gloomy weather, and a shy little flower blooms quietly on the moist earth. At that moment, dreams come gently like the tide, and the butterfly's mood flies among the dry branches with the cut sunshine. But when the last haze dissipates, the angel is exhausted."
The butterfly said: "The heart will go with love."
