雨打湿了我的心怎么写
[yŭ dă shī le wŏ de xīn zĕn me xiĕ]
It literally translates to 'how to write with my heart wetted by rain'. In this context, it portrays a sentiment of helplessness in describing deep feelings brought about by sorrow, akin to trying to express emotion while under the burden of intense grief or loss, similar to being in the rain and having one's heart drenched with water and emotions.
