As the saying goes: Reading thousands of books is not as good as traveling thousands of miles, and traveling thousands of miles is not as good as reading countless people. This sentence seems to put reading at the most superficial level, but in fact it goes full circle and returns to the beginning. Mr. Lin Yutang wrote in the article "The Art of Reading": Reading or the enjoyment of books has always been regarded as an elegant thing in a cultivated life. Compare the difference in life between a non-reader and a reader. The person who has not developed the habit of reading is imprisoned by the world in front of him in terms of time and space. But when he picked up a book, he immediately entered a different world. Such a change in environment has the same psychological impact as traveling.
