If you don't understand, you won't. You must understand and learn. Learning is to better adapt to the new development. Confucius said, "Learning is not enough." He said so.
Marx said: "Things always change and develop." For example, genetic variation, or aquatic development to terrestrial and so on. In this process, those who adapt to the environment will survive, and those who do not adapt to the environment will naturally be eliminated. People live like this in society. When they were born, they slowly learned to walk and talk, and gradually came into contact with all kinds of things in the process of growing up, so they have to learn a lot, such as dealing with daily things and interpersonal relationships. Some people are good at understanding. Therefore, they can easily cope with various environments. Some people are complacent and lazy to understand and learn, and as a result, they are at a loss and abandoned by the times and society. And the list goes on.
