After the Tang dynasty, a large number of works named after "thousand-character writings" also appeared. For example, Tang Yijing compiled a thousand-character Sanskrit, Song Huyin wrote a thousand-character narrative, Xia Yuantai wrote a thousand-character literary style, and so on, which shows the great influence of the thousand-character scripture. So why do thousands of words have such great charm?
First of all, literacy is a prerequisite for learning and Ming Dow. In ancient times, China attached great importance to "primary school" education, and the "thousand-character" has different shapes, covering almost all the structures and radicals in Chinese characters, and is an ideal model for literacy.
Secondly, Qian Wen Zi contains a lot of astronomical, geographical, historical and humanistic information, and it is a textbook of ancient Confucianism. In addition to literacy, it can also inspire children.
Thirdly, Qian Wen Zi is flowery in rhetoric, beautiful in writing, clear in rhyme, catchy and suitable for reciting. During the 400 years' circulation, the content of Qian Wen Zi has changed constantly, and different versions have appeared, which has influenced Japan, Korea and other countries and made great contributions to the spread of Chinese civilization.
I hope my answer can help you.
