(1) Enlightenment curve: Some of these people have learning disabilities, while others are not enlightened, just like "Ding Bai". Most of them have short academic qualifications, so their reading ability and thinking ability are blocked, and their ability to acquire knowledge through learning is obviously insufficient. The "dream line" is actually a low straight line. People living in "wisdom line" are mostly poor people at the bottom of society. People with congenital learning disabilities need social assistance.
(2) Early gratitude curve: Most of these people have received school education in adolescence, generally obtained high school education, mastered basic knowledge, and have the initial ability to acquire knowledge through learning. At this time 18-20 years old, the learning ability reached a high point. From then on, learning slackened and learning ability declined. Such as blooming flowers, wither prematurely, so they are called "early thanks line". Most of these people are middle and lower classes of society.
(3) Golden section curve: Most of these people continue to climb up their learning ability after obtaining high school education. Then go to colleges and universities for further study, and obtain relevant professional knowledge, professional skills, and corresponding higher education and degrees. At this time, the learning ability reached a new height, but then stopped the upward trend and slowly turned around. Most of these people are social middle forces.
(d) Excellent curve: Such people have not stopped studying after leaving university. After joining the organization, I started "secondary learning", combining learning with application. In middle school, learning ability continues to climb to a very high position. At the end of career, learning ability reaches the highest point, and then slowly declines. Most of these people are in the upper class of society.
(5) Wise curve: This kind of people's learning ability has been on the rise until the end of their lives. This is an all-round intelligent life and an intelligent life. Such people are outstanding top talents.
Throughout the ages, the basic trend of the development of human learning ability is that there are fewer and fewer Ding Bai and more and more wise people. The cultivation of learning ability is the cultivation of learning ability, that is, the cultivation from "wisdom" to "wisdom". The future is an era of learning, knowledge and wisdom. There is no Ding Bai who laughs and has a university.
