1, the meaning is more specific: Fang Fei usually refers to the blooming flowers in the fields, which vividly depicts the beautiful scene of spring and makes people feel the charm of nature and the power of life. In contrast, if the heart is like a wheatgrass, it is better to forget the specific image of wheatgrass than to describe the inner beauty and kindness more abstractly.
2. The literary expression is stronger: fancy grass is often used as a metaphor or symbol in literary works, which has strong expressive force and appeal. But if the heart is wild, it is more used to describe the beauty and kindness of the heart, and it is not suitable for describing people's appearance or personality characteristics.
