As the saying goes, those who do not seek the overall situation do not seek a domain. We have learned so much knowledge and read so many books, but we don't know how to use it at critical moments, so we should learn to build a knowledge framework when studying. So how to build a knowledge framework? Firstly, knowledge is classified. Knowledge Palace is a method of knowledge classification. The essence of learning is the process of building a temple of knowledge. Only by establishing a knowledge palace can we connect the learned knowledge into a system. With the knowledge palace, we can acquire knowledge quickly, accurately and effectively. So how do you build your own knowledge palace? Everyone's knowledge system is like a palace, different floors and different rooms, which constitutes a person's knowledge system. There are six steps to build a knowledge power supply, which must be firmly remembered. First, understand the total number of knowledge palaces. The total amount of knowledge palace is the sum of all knowledge systems in the whole knowledge palace. Second, build the structure of the knowledge palace. Then we need to know what is the knowledge system of each floor and what is the relationship between floors? Third, the learning process of mastering knowledge is to learn what you are learning first. Fourth, build the internal connection of knowledge. Every room has a theme, and you will have different knowledge points for each theme. Floor, room and small room are all connected floors. Fifth, sort out the external connection of knowledge. There may or may not be correlation between floors. Sixth, about the dynamic change of knowledge, we should know that the only constant is the change itself. We should always pay attention to the policies, national conditions and information of some industries to ensure complete control of dynamic knowledge.
