No, the Chinese did not use samurai swords. Samurai swords, specifically the katana, are associated with the warrior class of feudal Japan, known as samurais. The katana is a distinct type of sword characterized by its curved, single-edged blade, circular or squared guard (tsuba), and long grip that accommodates two hands.

In contrast, the Chinese have their own traditional swords, such as the jian, dao, and various regional variations. The jian is a double-edged straight sword, while the dao is a single-edged curved sword. These Chinese swords have different blade designs, hilt configurations, and cultural significance compared to the katana.

While there have been historical and cultural interactions between China and Japan throughout history, the Chinese and Japanese sword traditions developed independently and have their unique characteristics and styles. It is important to differentiate between the swords used by the Chinese and those used by the samurais in Japan.
