There was a famous monk named Shi Yaqi in the Tang Dynasty. He writes a good hand. Many collectors invited him to write and collect, and he was very happy. His calligraphy is like flowing water, very elegant.
Calligraphy attainments in the Asian period were acquired through hard practice. Because I have lived in a temple for a long time, I burn incense and recite scriptures every day. So I have a lot of free time to do other things. While other monks secretly play chess and sleep when they are free. Shiyalou is different. In his spare time, he bought pens, ink, paper and inkstones to practice calligraphy. Sometimes in the dead of night, he is still practicing hard. Day after day, year after year, he writes more and more deeply. His fame is getting bigger and bigger.
Many pilgrims came here to ask him to write. He also comes to the net and agrees one by one. His cursive script is particularly elegant and unrestrained. Someone asked him, "How to calculate cursive script?" Shi Yalou wrote eight words: "Birds out of the forest, frightened snakes into the grass!" " "It means that calligraphy can only be regarded as a bird in the forest and a frightened snake in the grass.
