Both the classical format and the Europeanization format are written format style, but their sources are different. The former mainly inherits the ancient Chinese, while the latter is mainly absorbed from other languages. Outwardly, the two seem to have distinct differences. However, our research results show that the occurrence frequency of the classical format and the Europeanization format that exist in several modern Chinese written formal format are keeping with two kinds of uniformity, that is the two have higher frequency than that appears in informal characteristic style; in addition, the style that appears in the classical format has the high frequency, so does the Europeanization format, and vice versa. This reflects that on the one hand, the formal written style has differences and contrariety with informal language style, on the other hand, its interior also has “conservative open” differences. Thus, Feng Shengli proposes that “elegance” is not the single internal standard to judge the differences of written formal style.
