Some people say that before dawn is the darkest, but Zhou Bingqian sings "I call for dawn in the night"

There are four seasons in a year, and after the end of the year, it is time to start again, counting a reincarnation, dividing the day and night, generally the hottest at noon, the darkest before dawn. So before dawn is not terrible, it is the inevitable of every day, if there is no sleep at the moment, listen to Zhou Bingqian's song, the sky is clear, the spirit is naturally vibrant. Life must go on, life will not go out, the struggle will not stop.
