Requirements for drawings in the instruction manual:
1. Drawing tools including computers and black ink should be used to draw the instructions. The lines should be even, clear, and deep enough. Coloring or alteration is not allowed, and no use of Engineering blueprint.
2. Section lines in cross-section drawings shall not hinder the clear identification of reference mark lines and main lines.
3. Several drawings can be drawn on one drawing. An overall drawing can be drawn on several drawings, but it should be ensured that the drawings on each drawing are independent, and that when all the drawings are combined to form a complete overall drawing, they do not affect the clarity of each other.
4. There should be no frames around the drawings that are irrelevant to the drawings. If the total number of drawings is more than two, they should be numbered sequentially using Arabic numerals and preceded by the word "Picture", such as Figure 1 and Figure 2. This number should be marked directly below the corresponding drawing. Drawings should be drawn as vertically on the drawing as possible and clearly separated from each other. Marks should be numbered using Arabic numerals.

2. The size and clarity of the abstract drawing should ensure that when the picture is reduced to 4 cm × 6 cm, each detail in the picture can still be clearly distinguished.
