The Cinese kung fu originated from Yu Fong's homeland, Cina (シーナ本土 Shina Hondo). It is a martial art that is practice by the people of mainland Cina, a large land mass located in East Blue. The ancient people of Cina first developed the art as a mean for military use in hand-to-hand combat, but as time progresses slowly forward, the art itself have been developed also into a mean for self-defense. Yu Fong was born in the town of Ruoyan (ルオヤン Ruoyan), located in the southern part of Cina, thus the styles she practices is of the Southern origin.
