It is best to look at it openly in life. Life is not long. Don't be proud when you are happy, and don't be frustrated when you are sad. It is not just you and me who are sad in the world. After going through ups and downs, maybe happiness is coming. Whether it is sadness or pain, we can't lose confidence in life. After all the wind and rain, what is presented in front of us is still the blue sky. In the years of the world, a sense of indifference and tranquility interprets the gratitude of life.
