[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings: Example 1 provides a practice sheet 1, such as Figures 1-10 As shown, the substrate includes a substrate 11, with a grid 2 on its front side. The grid lines 21 of the grid 2 are high-temperature vanishing lines. Alternatively, a background 3 is provided on the front side of the substrate 11, and the background 3 is a high-temperature vanishing pattern. Or, the front side of the substrate 11 has both a grid 2 and a background 3, where the grid lines 21 of the grid 2 are high-temperature vanishing lines, and the background is a high-temperature vanishing pattern or a fixed pattern. The grid lines 21 are formed by drawing or printing high-temperature vanishing sublimation ink on the substrate 11. The high-temperature vanishing sublimation ink is existing technology and can be commercially available products, specifically models S19 or A19. Colors can include dark gray, black, white, blue, red, or yellow, as well as traditional Chinese colors such as coral, amber, pinkish-purple, and pine green.

[0021] The grid lines 21 are drawn or printed using high-temperature disappearing lines. When practicing or writing, the grid lines 21 provide a reference and facilitate practice. After the artwork is completed, heating the practice paper 1 and its grid lines 21 will cause the grid lines 21 to disappear without affecting the aesthetics of the artwork, thus improving its appearance.

[0022] The disappearance temperature of grid line 21 is 55-65℃. Blank paper without grid lines is used as the substrate.

[0023] like Figure 1 In Example 2, grid 2 is a square grid, that is, a square grid 2 with a width of 1.8-2CM, but not limited to this.

[0024] like Figure 2 In Example 3, grid 2 is a vertical grid, with a width of 2cm and a length of 10-20cm, the length of which can be set according to the size of the paper. More specifically, the vertical grid can be designed as black lines, which are black grids used to standardize the lines of text in books made of silk or paper.

[0025] like Figure 3 Unlike Example 3, the practice paper 1 in Example 4 is a top scholar's paper, with corresponding markings on the vertical grid in the middle.

[0026] like Figure 4Unlike Example 2, grid 2 in Example 5 is a flat grid, that is, a rectangular grid with a size of 2*3cm. However, it is not limited to this and can also use circular grids, oval grids, cross-shaped grids, tile grids, and irregular grids. Figure 10 The shape of the tile is shown; Figure 11 The shape of some irregular lattices is shown.

[0027] Figure 5 The background 3 set on the exercise paper 1 is shown, but it is not limited to this; grids 2 can also be set on the background 3.

[0028] Example 6, as Figures 6-7 One side of the exercise paper 1 is provided with a binding part 5, which facilitates binding multiple exercise papers 1 into a book. More specifically, the binding part 5 is provided with multiple binding holes 51, and the binding element 52 is installed in the binding holes 51. Figure 6 Exercise sheets 1 can be bound into loose-leaf booklets, but this is not an exception.

[0029] like Figure 7 Optionally, a tear slit 53 is provided between the binding section 5 and the grid 2, allowing the practice paper 1 to be torn off through the tear slit 53 during practice or writing. The tear slit 53 consists of multiple spaced through holes; the work can also be torn off separately for storage or display after writing. Optionally, a magnetic attachment 4 or a magnet is provided on the underside of the practice paper 1, allowing the work to be easily attached to a refrigerator door, iron door, whiteboard, blackboard, etc., for convenient display. Preferably, the magnetic attachment 4 is a flexible magnetic attachment 4.

[0030] like Figure 8 Optionally, grid 2 also has a font slot 22, which provides practice assistance to the practitioner.

[0031] Example 7 provides a practice device, such as Figure 9 As shown, the device includes the aforementioned practice paper 1 and a heater 6. The heater 6 works in conjunction with the grid 2 to heat the grid 2 or the high-temperature disappearing curve. The heating temperature range of the heater 6 is 60-110℃, preferably 60-80℃. The structure of the heater 6 is existing technology and commercially available products such as heating plates or irons can be used; further details are omitted here.

[0032] The practice device may also include a practice pen 7, which the practitioner holds to write or draw on the grid 2 or background 3 of the practice paper 1. After completion, the grid 2 on the practice paper 1 is heated by a heater 6. The high temperature causes the heat disappearance lines of the grid 2 to disappear, making the artwork more aesthetically pleasing. After the artwork is torn from the binding part 5, it can be displayed or hung, such as by using magnetism to attach the artwork to a whiteboard or refrigerator door.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
