It's unrealistic to practice calligraphy at this age, but it's ok to practice your signature well. Because normal signatures are relatively formal running scripts, if the foundation is not good, the structure is not well grasped, and it is not beautiful to write, it depends on personal needs and usage occasions. However, the signature that needs to be recognized can be simplified appropriately and designed with a strong sense of font connection. As long as the written style can create momentum, it is not difficult to practice if the font is Lian Bi. If you feel that you can't write well, you can abstract generalization, have a rough outline of Chinese characters, and have a minimalist font or a fit design. However, this kind of signature has low recognition and is suitable for anti-counterfeiting contracts.
