This paper explores the calligraphy thoughts and calligraphy of Zen-Master Dokuryu Shoueki (1596-1672; whose real name is Guanyin Tai and who changed his name to Daili, with the courtesy name of Man Gong and style name of He Ji and Tianxian Laoren) who traveled to Japan in the late Ming Dynasty. In addition to his personal subjectivity in the Six Methods of forming Chinese and center tip artistic persistence, his concern for calligraphy also included his cautious words and deeds and sense of mission that claimed to be the orthodox Chinese calligraphy. Therefore, his independent criticism of the Japanese calligraphy culture at that time is observable and his motivation for writing calligraphy works is also understandable.
