It is recommended not to use round bodies for grades 4 and 6. Let's put it this way: not all teachers are used to seeing circles, but all teachers will not reject printing. Round Chinese characters are a very beautiful word. Although you can write in any style, you must ensure that the marking teacher can see your spelling clearly, without any trouble, and the surface of the paper is clean and tidy. On this premise, you must answer questions within a limited time. Personally, I think it is difficult to do it under normal circumstances. Moreover, the purpose of the exam is to get high marks. If you can't effectively identify the round body, it will still be a disadvantage to deduct points (although CET-4 and CET-6 can be tested many times, it is better to try to pass it once and try to reduce unnecessary deduction items).

Round body is a domestic saying. In fact, there is no word "round body" in English calligraphy. Real circles include lettering, English circles, commercial calligraphy, decorative calligraphy and so on. Except for business calligraphy, you can use ordinary fountain pens, and all others should use professional oblique dip pens. In China, the so-called round Chinese characters look like copperplate, but there is no thickness change and gorgeous decoration, which is an extension of English calligraphy and daily life, and it is more casual. And printing, that is, we often say Hengshui. Horizontal and vertical, just like printed. Using this font in the exam can not only let the marking teacher see what is written at a glance, but also avoid visual fatigue.
