At this time Shinkō Okina was 17 years old.
In Manchuria he lived together with bazoku (mounted bandits/rebels) and made a living from hunting, during which he learned to use the Suruchin, the throwing art of Shuriken-jutsu and went through a general martial way of live.
In Fuzhou the house of the parents of Go Kenki (in Fujian, Fuzhou-city, Minamidai Suifukan this-and-that-street or -district) became the center and beginning of the activities, where he was taught by [Go Kenki’s] father Go Kōki in Fujian Shōrin-ken, and than Go Kōki introduced him to his life-long master, Kingai Rōshi [„old master “ Kingai] (Shū Shiwa’s older student).
The teaching of Kingai Rōshi was very strict. The secret of the Bujutsu of the family tadition is, that is is done mutually. Concerning the exact origin: father and grandfather have been taught Kenpō and were very capable of it. The Kenpō was tiger- (tora) and crane (tsuru)–style, with the Kenpō of Sanchin as its core, and the Fujian Shōrin-ken Kata Seisan-ho, Gojūshi-ho, Gojushichi-ho and Bunkai-training.
The Gokui (the secret principle; innermost core) of Rōshin’s teaching was the „Hit-Person-Method“."
I took and interpreted this from a memorial booklet called "KO MATAYOSHI SHINPÔ TSUITÔ. Matayoshi Kobudô Tôde-dô Kokusai Enbu Taikai." It's quite interesting.
