In old China, happiness means the family getting together or the family tree is large and the daughters and sons are very kind to the parents. While in modern times, the meaning of happiness is changing, in my opinion, today, happiness means achievement. For some people, the achievement of the work brings them fulfillment, they are satisfied with the achievement they have made. When they are off work, some may feel lonely and lose signs of life. For other people, an achievement in life brings them more happiness. They like to make friends, they are welcomed by the people around them, which makes them feel valued. No matter what people take the judgment of happiness, there is no doubt that they are focusing on their inner emotions, it reveals that people take care more about themselves.
