Mark Twain, who had a very rich and exciting life, was not an ivory tower writer. Because his reputation was not high, at the beginning of the film, the daughter's classmate struck: "My father said Mark Twain was only a third-rate writer, and his speeches contained only some undernourished anecdotes and jokes about strange people."

Mark Twain stopped going to school early in his youth, had no ambition, spent his days smoking a pipe, and had no plan for his life at all. In general, young people in this situation, always meet some older people who would like to give suggestions, but the proud shallow young people always do not listen. In the film Mark Twain did a good job. He certainly knew very well that if life's experiences can be copied, the value of life will be greatly diminished.

Chinese culture advocates "读万卷书 行万里路", which is consistent with Mark Twain's attitude. In order to break through the limitations of one's physical body, one has the way to acquire the information of the whole world through communication channels. But after the virtual learning, it is still necessary to practice in the flesh, which is called "尽信书不如无书".

What Mark Twain said to the young people was more than that, and he did not value what he said, but it was such sincerity that moved all the students and made "Roughing it" more meaningful.
