Test analysis: This question examines students' ability to read historical materials and use knowledge. Wang Sengqian, a calligrapher in the Southern Dynasties, said in his book Ode to Literature: "The wonderful way of books is that the spirit is the highest, and the form and quality are the second. Both of them can be better than the ancients." It emphasizes that form is used to write spirit, both form and spirit are. According to this analysis, it can be seen that C meets the meaning of the question, while ABD does not meet the main idea of the material. So choose C.
