Although he remained true to the teachings of these two great masters, Mabuni sought instruction from a number of other teachers, including Seishō Arakaki, Tawada Shimboku, Sueyoshi Jino and Wu Xiangui (a Chinese whitecrane kungfu master known as Go-Kenki in japanese). In fact, Mabuni was legendary for his encyclopaedic knowledge of "kata" and their "bunkai" applications. By the 1920s, he was regarded as the foremost authority on Okinawan "kata" and their history and was much sought after as a teacher by his contemporaries. There is even some evidence that his expertise was sought out in China, as well as in Okinawa and mainland Japan. As a police officer, he taught local law enforcement officers and at the behest of his teacher Itosu, began instruction in the various grammar schools in Shuri and Naha.
