In Han Dong's works, "Mountain Man" is not a diligent and patient person like Yu Gong. He is even a big slacker-he feels "very tired" just because he thinks that "a son's son will have a son". Do you think you can expect such a person who is tired of "thinking" to "do" a long and arduous trip? Therefore, this "mountain man" is completely different from Yu Gong. The bigger difference is the back. Since I want to see the "far sea" and am lazy, what about the "mountain people"? Han Dong wrote: "He just regretted that his ancestors didn't think like him, otherwise, it would be his turn to see the sea"-"Mountain Man" put the blame on their ancestors. What about him? He doesn't want to "start from me, start from now" in order to realize his wish to see the sea. He hopes that his ancestors can think like him and then do it, so that they can enjoy themselves-watching the sea. We can see that this "mountain man" is not only a lazy person, but also a person who "just wants to enjoy the cool". Selfish people who don't want to plant trees. "
