You have to taste the ups and downs of life. . . It’s just like cooking and eating. Some people like sweet, some like sour. Sometimes they also eat bitter vegetables (bitter melon, wild vegetables). Bitter vegetables reduce heat, and some also lower blood lipids. It is very appropriate to refer to the ups and downs of life experience and growth. . For example, when you encounter difficulties at work or in study that are difficult for ordinary people to overcome, you use "bitterness" to describe them, etc. . . Only by tasting all the warmth and coldness of the world can we grow. . . We were not sensible when we were young, but we grew up slowly in the warm embrace of adults. The growth here should be said to be maturity. When we go to school or work or struggle alone, and no one is with us, we have to take care of ourselves. At this time, we feel the warmth and coldness, and think of our parents. At this time, we become responsible and mature. . . . It is difficult to study and work, because we are here to solve the difficulties in the world. In this way, as we experience more and more, we will naturally master study and work, and people will grow up, mature, and become strong and powerful. . . . . . Life is beautiful and sweet. As long as you dare to face difficulties, are not afraid of them, and overcome them, they will give way to you. It is not advisable to avoid or retreat from the mediocre approach. The only way is to face reality, treat it correctly, and solve it with wisdom. . . .
