Calligraphy is an excellent traditional culture in China. Learning calligraphy can cultivate sentiment and temper people's will; Writing is also an important symbol to measure a person's Chinese accomplishment. Although mobile phones, telephones and the Internet are well developed, it is inevitable to start writing. Neat pen writing conveys accurate information and is not easy to delay. Ordinary people should at least do this. It would be more ideal if it were beautifully written with pen and ink. It can be used in many occasions, such as signing, taking a written test, etc. It can set off your cultural accomplishment, just like a deformed business card! Of course, after work, signatures and the like should look good. We often say that this man's handwriting is good, and he can achieve great things at a glance. On the contrary, this person's handwriting is scrawled and always feels different.
