Only snowflakes know what I mean. They write down the lovesickness all over the sky.

Only snowflakes know what I mean, and write down the lovesickness all over the sky. It means: if snowflakes don't understand my feelings, how can I spread acacia all over the sky in the form of snowflakes?

Only snowflakes know what I mean, and write down the lovesickness all over the sky. That is to say, if snowflakes don't understand my feelings, how can they spread acacia all over the sky in the form of snowflakes? This poem expresses its feelings of lovesickness by describing snowflakes all over the sky.

The lyrics "Only the snowflake knows what I mean, and I wrote the lovesickness all over the sky" comes from the song "Love in the Snow", written by Li Guo.
