Confucianism holds that without virtue, one cannot obtain happiness. The happiness of life is reflected in personal good deeds. The process of people's continuous improvement of personal virtue is the process of pursuing happiness. In order to cultivate virtue, one cannot adhere to material life. Even if it is "a meal, a drink", as long as you can cultivate high morals, such ascetic behavior is happy. The text is intended to emphasize:. ['How people promote personal virtues.', 'Having virtue is a prerequisite for happiness.', 'How happiness manifests in good deeds.', 'The interrelationship between virtue and happiness.']
