The first sentence in "Persuading to Learn" is a classic.
That is to say, all people are born equal, not born with different ranks. But if we look around today's human world, we will see that there are sages and fools, poor and rich, and noble and noble. There seems to be a world of difference between them. What makes these differences is learning and not learning.
There is no difference between being rich and poor in life. Only those who are diligent in learning can be rich, and those who have no learning will become poor.
This paper discusses the importance of learning and advocates practical learning.
