No, samurais are not Chinese. The samurais were a distinct class of warriors in feudal Japan who held a significant role in Japanese society and history. They emerged during the Heian period (794-1185) and reached their peak during the feudal era, specifically the Kamakura (1185-1333) and Edo (1603-1868) periods.

The term "samurai" refers to the military nobility of Japan who served as retainers to daimyos (feudal lords) or directly to the Shogunate (military government). They were skilled in martial arts, trained in warfare, and practiced a code of conduct called Bushido, which emphasized loyalty, honor, and self-discipline.

Chinese history has its own warrior class known as "wu-shi" or "wu-ren" (warriors), which includes various categories of warriors such as knights, generals, or soldiers. The samurais are specific to Japanese history and culture and should not be confused with Chinese warriors.

It's important to recognize the distinctions between different cultures and their respective historical figures and institutions. While both China and Japan have rich martial traditions, they have distinct histories and cultural identities.
