If your children want to learn to draw, they can consider sketching or traditional Chinese painting. The following is a comparison of the two forms of painting:

1. Sketch: As the basis of painting, learning sketch can help children master painting techniques such as lines, light and shade, and three-dimensionality. This technique is used in both Chinese and Western paintings. However, the learning of sketching may not be suitable for children's acceptance and understanding abilities as well as the lively and moving characteristics brought by their age, and children may find it difficult to master.

2. Traditional Chinese painting: The study of traditional Chinese painting can help you master the painting skills more comprehensively, and is also helpful for the study of other art subjects. The study of traditional Chinese painting can cultivate children's open thinking and aesthetic ability, while also allowing them to understand traditional Chinese culture. However, learning Chinese painting may require some patience and time, as it requires mastering some basic skills, such as the mastery of pen and ink.

In short, choosing between sketching and Chinese painting depends on the child's personal interests and learning ability. If your child likes challenges and can learn patiently, then learning to sketch may be a good choice. If your child wants to have a deeper understanding of traditional Chinese culture and has enough patience to learn, then learning Chinese painting may be more appropriate. No matter which form of painting you choose, you need to find a good teacher to guide your child's learning.
