The calligraphy is good.
1. The art form is good. The advantage of calligraphy is that it incorporates dot and stroke techniques, making it an art form that conveys emotions and has the value of appreciating beauty. Hard-pen signatures are more common and are not as good as the art form of calligraphy.
2. Good stability. The key to good calligraphy writing is to have a peaceful mind, which leads to better stability and less error. Hard-pen signatures are sometimes difficult to control and are affected by ink, paper and other factors, and are not as stable as calligraphy.
