I have heard that Vietnam has a form of wing chun that developed outside of Hong Kong but is this really Vietnamese wing chun? I've seen other footage of Vietnamese wing chun and this looks totally different. This looks more like a mish mash of various wushu forms including bagua, nan chuan, and weapons forms.
the criticism of the kettle is really on point, they recommend starting with geography and realizing what is North and South Vietnam, yes there are many styles of wing chun, only a kettle is a kettle 😁🙏
