No, the Chinese did not have katanas. The katana is a specific type of traditional Japanese sword that originated in Japan and is closely associated with the samurai warriors of feudal Japan. It is characterized by its curved, single-edged blade, circular or squared guard (tsuba), and long grip that accommodates two hands.

Chinese swords, on the other hand, have their own distinct designs and styles, such as the jian and dao. The jian is a straight, double-edged sword, while the dao is a single-edged sword with a curved blade. These Chinese swords have different blade shapes, hilt configurations, and cultural significance compared to the katana.

While there has been historical and cultural exchange between China and Japan, the Chinese and Japanese sword traditions developed independently and have their own unique characteristics. It's important to differentiate between the swords used by the Chinese and those used by the samurais in Japan.
