About So-San
So-San was the pen name of the monk Choi Hyong Ung (1520-1604) of the Lee Dynasty. At the age of 72 — the pattern's movement count — he raised a corps of fighting monks alongside his pupil Sa Myung Dang, and together they helped drive back the Japanese who had overrun most of the peninsula in 1592.
