(2) black body. Blackbody can be divided into blackbody and long black. Bold is named after "the font is thick and the box is black". The characteristics of black body are: uniform thickness, square head and square tail. So it is also called "cube". The style is rich, simple, generous and attractive. Mainly applicable to titles, slogans, etc. In addition, it should be noted that bold font is the most suitable font for beginners to practice because of its rigorous structure and concise strokes. Although the stroke width of bold characters is the same, it can't be absolute, and it can't be the same depending on the number of strokes of bold characters. Chinese characters are generally more horizontal and less vertical. Some strokes are too many, and they are congested when writing, so they can't write; And words with few strokes, even if they use the same width, feel empty. Therefore, appropriate adjustments should be made between the long and short strokes, the horizontal and vertical strokes and the thick and thin strokes to achieve the overall unified and coordinated effect. In addition, when writing in bold, the two ends and tips of the strokes should be properly strengthened to make them more thick and powerful.
