Walking out of the long night, you can see the dawn. No matter how long the night is, there will always be a day of dawn. No matter how many difficulties there are, there will be a beautiful day and life will become interesting and bright. I believe all this is beautiful. This is a metaphor. It is dawn after a long night. The long night refers to the immediate difficulties. Walking through the night to meet the dawn means that everything goes well after going through difficulties.
