Yu Lao once said: with the progress of science, writing is also simple. Printing is printing, and cursive is cursive, which is convenient for Xi. He believes that "writing is a tool for human beings to express their thoughts and develop their lives. Its ingenious structure and ease of use are crucial to the future of the nation! " He thinks Chinese characters are too difficult to recognize and write. In order to "seek the convenience of making, give full play to the cultural function, save the time of the whole people and give full play to the sharp weapon of the national tradition", he took the advantages of hundreds of cursive scripts and created standardized cursive scripts, with the aim of "accepting the culture of our country for thousands of years and carrying it forward." And set aside (save) a lot of time for children and grandchildren every day to increase the efficiency of their careers. "He has a wonderful metaphor for all kinds of fonts. He said: "Regular script is like a line, running script is like a boat, cursive script is like flying. "In order to do something practical for the people, he initiated the establishment of a standard cursive script society in 1932 to standardize cursive script and restore its writing function. After years of efforts by him and the cursive society, the book "Cursive Grass" was revised nine times before his death, published six times in Chinese mainland and three times in Taiwan Province.
