The earliest writing has a history of about 3500 years, which is a remarkable feature of the evolution of human history. With the improvement of calligraphy, the level of ideological understanding and aesthetic taste will also improve. Domestic research shows that people who like to practice calligraphy have more frequent brain activities (meditation) than ordinary people. Regular thinking will make the brain develop and exercise accordingly, effectively promote the vitality of brain tissue and increase memory ability. Science and technology is a double-edged sword, which enables human beings to develop a large number of resources. Uncontrolled exploitation and utilization will lead to the imbalance of natural ecosystem and the slow extinction of species. Isaac asimov, a famous science fiction writer, mentioned in his works that "the emergence of science and technology stems from people's laziness". With the excessive development of science and technology, human beings began to lose some of their original abilities. For example, the ability of human beings to survive in the wild is almost non-existent, and the ability to prevent diseases is also weakening. Some people may say: why don't you go and see those people who have good survival ability in the wild (Baye, Deye) and good disease resistance? I want to say, please don't generalize. Now back to my (positive) subjective argument, technology has certainly made human life better, but we can't forget the crystallization of the world's culture for thousands of years, and the inheritance of culture is more important than technology.
