They say that life is fragrance, sour, sour, sour, sour, sour, sour, sour, sour, sour, sour, sour, sour, sour. It is hoped that our lives will be much sweeter, sometimes salty, sour and spicy, and that bitterness will always stay away from us. When you think about it, life is not hard and it's not too real. If bitterness is a necessary experience in life, let it be sweet, and always just a little bit of life in our lives。
