There is a flowing word in the calligraphy inscription, which I didn't write. . Is there something wrong?

Hello, your friend wrote it correctly. The word "Liu" can be added or not at the top right. Many calligraphers don't get extra points, which is a kind of calligraphy stress.

First, calligraphy is art, and art has artistic characteristics. Painting more and painting less is the need of artistic beauty;

China Chinese characters and China civilization have a long history. Many Chinese characters have many ways of writing, some of which are only known by a few professionals.

Art comes from reality, but it is not bound by reality.

Therefore, when you are writing, you don't have to pay attention to these.

I'd like to introduce a good book: Yu Youren Calligraphy Dictionary, which contains many ways to write each Chinese character.
