1. Education can be divided into broad sense and narrow sense. Education in a broad sense generally refers to all practical activities that purposefully affect people's physical and mental development and social functions, as well as the inheritance and development of human history and national civilizations. In a narrow sense, education refers to the education of specialized and organized institutions, which is an activity to guide the educated to acquire knowledge and skills, cultivate ideological and moral character, and develop intelligence and physical strength in a purposeful, planned, organized and systematic way according to the actual and future needs of the background society. Education has a profound impact on the development of human culture, not only to convey culture, but also to meet the requirements of the continuation and renewal of culture itself.

2. Different times and countries have different understandings of education. Educators with different historical backgrounds will admire different educational goals and methods. Confucius said: "The way of a university lies in virtue, in being close to the people and in perfection". Mencius believes that "it is also a pleasure to be educated by talents in the world." Lu Xun emphasized that "education is to cultivate people". Tao Xingzhi believes that education is a "life education" based on life and oriented to life, and cultivates people with action ability, thinking ability and creativity. Dewey said that "education is life". Spencer in Britain believes that "education is to prepare for future life". By integrating the ideas of educators from different times and countries, we can appreciate the essence of education.

3. Education is a basic human need, a right and an obligation. Early education in Europe was greatly influenced by religion, and ancient education in China began with classic works. Education in today's society aims to improve people's knowledge and skills, influence people's ideology and morality, and enhance people's physique.

The object of education is people, so the content of education must be benign and meaningful. Educators play a leading role in educational activities, planning and managing the direction and objectives of educational activities, as well as the contents and methods of transmitting information. Educating and educating people is to make people accept all kinds of useful knowledge, so as to absorb and internalize this knowledge and directly apply it to society, or to sublimate new knowledge based on this knowledge, that is, discovery and invention, so as to promote social development and human civilization.
