In the Disney animated film "Mulan," the protagonist Mulan wields a sword known as a Jian. The Jian is a traditional Chinese double-edged straight sword with a typically slender and pointed blade. It is one of the most iconic and historically significant weapons in Chinese culture.

In the movie, Mulan's Jian is depicted as a symbol of her strength, courage, and martial skill. It plays a central role in her transformation and her journey as a warrior. The design of the sword in the film incorporates artistic elements and reflects the aesthetics of Chinese swords, although some artistic liberties may have been taken for storytelling and visual appeal.

It's important to note that there have been different adaptations of the Mulan story over time, including live-action films, TV shows, and theatrical performances. The specific portrayal of Mulan's sword may vary across different adaptations, and each interpretation may feature slight variations in design and artistic style.
