Happiness, of course. What is happiness? In fact, happiness is just a feeling of being satisfied. People who have no money think that eating well and wearing warm clothes is happiness, rich people think that emotional enrichment is happiness, young people think that family happiness is happiness, old people think that their children and grandchildren are happy, beggars think that they can eat enough, and people trapped in cages think that freedom is happiness. Therefore, happiness will be felt differently due to different environments and social levels. However, in this life, no matter what your world outlook and values are, you must work hard to feel happy, and you will never knock on the door yourself. Since you have come to this world, you should live well, take every step with value, give your family a stable and rich living environment and give yourself a free and easy life. This should be the pursuit of ordinary people.
