What's the use of the central point in Tian Zige?

Regular script is the basis of calligraphy, so writing regular script in a standard, symmetrical and beautiful way is the primary task of learning calligraphy and the basic requirement for primary and secondary school students to write Chinese characters well. Many experts studying calligraphy in ancient and modern times invented many writing grids, such as Tian Zige, Mi Zige, Jiugong Grid, Tian Huige, Gong Huige and Wuhuan Grid, in order to let beginners master the stroke positioning and grid structure of regular script as soon as possible. They have their own characteristics. For example, Tian Zige can help us grasp the center of gravity of a word and standardize the structure of Chinese characters. Mi Zige has two more diagonal lines than Tian Zi, which can not only help to deal with the center of gravity of a word, but also provide a model for the scribbling arrangement of a word; Jiugongge is divided into nine small squares with up and down horizontal lines, left and right straight lines. The square in the middle is called Zhonggong, which is convenient for grasping the center position and center of gravity of the text when writing. Horizontal and vertical lines are used to arrange the division of words, and diagonal lines of squares can be used for comparison. Many other writing boxes have been added on the basis of these three traditional formats. Although they are all helpful for beginners to learn regular script, they all have a common major defect, that is, the writer can't intuitively determine the size of regular script Chinese characters in various grids, can't scientifically grasp the relatively fixed positioning law of Chinese characters, can't stably guide the writer to write a grid, and is time-consuming and laborious, so it is difficult to develop scientifically and sustainably.

Summary of the invention

The technical problem to be solved by the invention is to overcome the shortcomings of the prior art, provide a new Tian Zige writing format, and locate the writing grid in Tian Zi with Tian Zige as the center, which can help writers find scientific writing rules and improve learning efficiency. The technical scheme adopted by the invention to solve the technical problem is that the writing grid with the center Tian Zi positioning comprises a square outer box composed of solid lines, an inner Tian Zi grid composed of dotted lines or dots is arranged in the square outer box, the center point of the inner Tian Zi grid coincides with the square outer box, and the ratio of the side length of the square outer box to the height and width of the inner Tian Zige is 8: 7: 7: 3: 3. The most preferred scheme of the central Tian Zi positioning writing lattice of the present invention is that the ratio of the side length of the square outer box to the height and width of the inner Tian Zige is 8: 5: 4 or 8: 4: 5. The existing frames in Tian Zige are basically composed of solid lines, so when writing, words are easily written on solid lines, which will easily affect fonts; In the present invention, the internal Tian Zi lattice is formed in the form of dotted lines or dots, and even if the font is written on the dotted lines or dots, it will not affect the font. The ratio of the square box to the inner Tian Zige is set according to the standard writing format ratio of regular script or official script, and the writer can enlarge or reduce it according to the needs of the font size. The inner Tian Zi case is the writing range of the font, and the ratio of the square outer box to the inner Tian Zige makes the whole writing range appear full and symmetrical in the square outer box, neither too big nor too small, which defines a moderate size for people who write in the air. The inner Tian Zi lattice is rectangular or square. As a further design of the technical scheme, the side length of the square outer box is 20mm, and the height and width of the inner Tian Zige are 12. 5mm and10 mm respectively; Or the side length of the square outer box is 14. The height and width of the inner Tian Zige are 9mm and 7mm respectively. 2mm respectively. When the ratio of the side length of the square outer box to the height and width of the inner Tian Zige is 8:5:4, it is suitable for the vertical layout ratio of standard regular script, regular script and small seal script. The basic format ratio of the central Tian Zi positioning writing grid is: the side length of the square outer box is 20mm, and the height and width of the inner Tian Zi grid are 12. 5mm and10 mm respectively; However, the writing format that is more suitable for hard pen lower case and brush lower case is that the side length of the square outer box is 14. The height and width of the inner Tian Zige are 9mm and 7mm respectively. 2mm respectively. The size of the square outer box is very consistent with the conventional size of the small box with the side length of 14mm to 15mm; Inner Tian Zi grid is the writing range of the main part of Chinese character book. Its width is half of the side length of the square outer box and its height is five-eighths of the height of a regular square, which makes the whole writing range look full and symmetrical in the square box, neither too big nor too small, and defines a moderate size for the written Chinese characters. The aspect ratio of Inner Tian Zige is 5: 4, which is just in line with the aspect ratio of the main part of China's regular script. As a further design of the above technical scheme, the side length of the square outer box is 20mm, and the height and width of the inner Tian Zige are10mm and10mm respectively.
