" much of what we today know as old-school Karate was basically cooked up in, and around, Matsuyama park, as it was a natural meeting place for Chinese experts wishing to practice their native fighting art and enthusiastic Okinawan youngsters wishing to learn stuff?
PM: Indeed I believe these embryonic circumstances cradled the birth of many famous Kata such as Suparinpei, Sanseru, Seisan, Kururunfa, and Seipai, etc.. In spite of Sanchin-like practices, which are commonly found in many southern Quanfa styles, and in spite of locating different Kata 型/形 - Xing that use identical names
i.e., Seisan/13, Seipai/18, Sanseru/36 and Suparinpei/108, etc., the said Kata are not practiced or taught in any southern Quanfa style, nor has anyone to date been able to locate such practices!
JE: Ironic, isn’t it?
PM: However, not being able to locate these Kata in China doesn't mean that we cannot find pretty much identical smaller templates #1 in many Southern-based Quanfa styles
i.e., Yongchun, Southern Praying Mantis and Monk Fist Boxing, etc.. Indeed, we most certainly can and have."
