A. Confucius: "Similar in sex, but distant in learning from each other"

B. Mencius: "It is better to believe in books than to have no books"

C. Mozi: "The existence of Tao is the existence of teachers"

D. Xunzi: "\" "

the answer is C.

Option A comes from Confucius' The Analects of Confucius Yang Huo, which means that human nature is similar, but they are different because of different habits and dyes. Option b comes from Mencius. With all my heart. It means that when reading, we should analyze it. We should not blindly believe in books, and we should look at problems dialectically. Option C comes from the Korean version of Shi Shuo, which means that where truth (justice) is located, Mr. (teacher) will always exist. For example, where is the truth, where is the real teacher. Option D comes from Xunzi's "Persuade to Learn", which means that the leap of a swift horse is less than ten steps, while the old horse doesn't go far, but he doesn't give up. In contrast, of course, the old horse has gone further. This metaphor for learning shows that we should persevere. So choose C.
