Melting snow is always colder than snow. Where did it come from?

The last sentence is: there is no one who doesn't work hard. The original sentence is: if the bald head can be replaced by snow, nothing is difficult in the world. Today, if you are around, there is no need to pour snow on your head.

Melting snow is always colder than snow, and the ending is always gentler than the beginning of the story, but the ending is not worthy of this beginning. People often say that "if it rains with snow today, it will be bald in this life", but they don't know the next sentence, "If the bald head can be replaced with snow, there will be no hard-working people in this life"
