1. Different shaping methods
Line drawing - the main shaping method of Chinese painting. Line drawing is a method that uses the weight, shade, thickness, virtuality and solidity, length and other strokes of lines to express the volume, shape, texture, volume and movement of objects. The characteristics are concise and clear, and can depict various phenomena.
Sketch is a painting that uses a single color to express changes in brightness. Painting tools are used to intentionally shape the shape of objects on the picture carrier according to certain drawing principles. Sketching is a variation of sketching. Sketching level is one of the important indicators that reflects the painter's spatial modeling ability.
2. Different expression effects

Extended information:
In Chinese painting, line drawing is not only a type of painting with independent artistic value (line drawing), but also a means of training basic modeling skills, and it is also a step before gongbi painting and coloring. process. Line drawing can not only outline static outlines, but also express dynamic rhythm. Using lines and spaces, you can also compose a concerto of harmoniously flowing lines.
Chinese painters of all ages have a profound understanding of lines and superb creations. They use various forms of lines to express emotions and depict nature, giving "line" a unique charm in works of art.
Line drawing is also called white drawing, which is simply drawing with lines. In line drawing, the lines can have many changes, such as length, thickness, curvature, density, weight, hardness and rhythm, etc. Line sketchers should pay attention to correctly expressing the front-to-back occlusion relationship of objects. Generally speaking, the baseline of nearby objects in the picture should be lower than the baseline of distant objects.
In order to better express the beauty of lines, we cannot draw whatever we see in sketching. We should make purposeful selection, refinement and processing through comparison and feeling. Commonly used lines include straight lines, arcs, curves and polylines.
Drawing is the foundation and skeleton of painting; it is also the art that is most restrained and requires the assistance of reason. Beginners to painting must first learn sketching. Those who are good at sketching will naturally be good at oil painting. The origin of sketching generally begins with the Renaissance. In fact, Greek vase paintings and sculptures all have a good foundation in sketching.
In the early days, sketches were regarded as the drafts of paintings. For example, when making a mural, you first need to have a draft of the idea, then a draft of the sketch, and at the same time, you need to have precise sketches of the hands and face. It is customary to make murals without looking at models for sketching. It depends entirely on the practice sketches prepared in advance and the artist's memory. Modern sketches have been separated from the original status of manuscripts and exercises and can be appreciated as works of art.
The attitude of sketching not only cultivates the descriptive power, but also cultivates the modeling ability. In the end, just the sketch can be appreciated as a work. On the contrary, just looking at the oil paintings can tell you how accomplished the artist is in sketching. Therefore, sketching is the basis of painting and the skeleton of painting. Beginners should learn sketching seriously first no matter what.
Strictly speaking, sketches are only monochromatic black and white, but if pastels or colors are added, they can still be recognized as sketches. Junyouhui's art documents are divided according to the expression method of sketch:

2. The subject matter can be divided into plaster sketches, landscape sketches, still life sketches, human figure sketches and fantasy sketches.
