tangzhuang
A tangzhuang (Simplified Chinese: 唐装) is a kind of pseudo-traditional Chinese jacket, typically with a mandarin collar.
It originated at the end of the Qing Dynasty (1644-1911) as an evolution of the Manchurian magua, which had been adopted by the Han Chinese during the Qing Dynasty. At that time, only noblemen, aristocracy and government officials wore it, however, in modern times it was eventually adopted by common people. This kind of clothing is often seen as a national costume for men, although women wear it as well.
Saotome Ranma from Ranma 1/2 is usually seen wearing this type of jacket.
