1, no brokenhearted, no love; You don't know life without setbacks.
2. Love is demanding, because demanding is short-lived. Friendship is tolerant because it lasts.
3. Really touching people's feelings is always unpretentious. It is silent, unobtrusive and buried deep in the heart.
4. The lowest realm of life is ordinary, followed by extraordinary and refined, and the highest realm is ordinary.
