Introduction
When you stretch your bare hands in the biting cold wind, and you feel the biting cold in your heart, that is the biting cold; if you feel nothing in your heart, then there is nothing. But even if you are used to the cold, don't care about the cold, and tell yourself that the pain is not real and you already believe it, when the long-awaited warmth gradually approaches, before you feel the warmth, you will shiver involuntarily, and then feel the cold to the bone-piercing pain.
Some people can't resist it, push away the temperature far away, and continue to feel the pain; some people chase it closely, just like chasing a beam of light that suddenly appears in the darkness for a long time, dazzling, but without hesitation.
