Kang Youwei's calligraphy is called "keeping fit" and "breaking the body", and his calligraphy has always been praised and criticized differently. Some people think that the writing of health and recreation is mainly flat and long arc, and the turning point is mainly round. The unique coarse, muddy and thick effect of long-ago wool is well reflected in his books, which is completely different from Zhao's frustration and rhythmic flow, and from He's single-round strength and rare dry pen, which is his unique place; Others think that Kang Youwei's lines have no texture, and he is vain because of his abuse of flying white.
The main reason is that Kang Youwei's calligraphy often starts without a sharp point, closes without a sharp point, raises without a sharp point, has a single line and lacks changes. Therefore, when sketching, you will see a loose void, which is not urgent enough and is a disease. And lack of ink, lack of expression, full of thick ink from the pen, see flying white in the pen, that's all.
Generally speaking, I think the disadvantages outweigh the advantages. I suggest you just read at most, and never learn ~ ~ ~
