Hello, Congge. This is the fourth letter I wrote to you. 2024.06.26

We can hardly understand the value of big cakes by listening to others say how good big cakes are and how much money they can make.

There is only one way to deeply understand big cakes, and that is to spend a year writing an article about big cakes every day.

If you are not willing to spend this time, don't expect him to understand the value of big cakes. All communication is in vain. Only in this way can you convince yourself, there is no other way.

Without output, all inputs are fleeting and floating clouds.
