Mulan is a legendary figure from Chinese folklore, and her age is not specified in the original tales. However, in the 1998 Disney animated film “Mulan,” the character is portrayed as a teenager who is roughly 16-18 years old.

In the film, Mulan is depicted as a young woman who is struggling to conform to the strict societal norms of her time, which dictate that women should be demure and obedient. Despite her family’s expectations that she will marry and bring honor to her household, Mulan is determined to prove herself by enlisting in the army in her father’s place when he is called to serve.
Mulan’s love interest in the film is Captain Li Shang, a military commander who is roughly in his early 20s. Like Mulan, Shang is depicted as a brave and capable warrior who is committed to serving his country. Over the course of the film, Mulan and Shang develop a mutual respect and admiration for each other, and eventually become romantically involved.
It’s worth noting that the ages of Mulan and Shang can vary depending on the version of the story or adaptation in question. For example, in the 2020 live-action remake of “Mulan,” the characters are portrayed as being somewhat older, with Mulan being in her late teens or early 20s and Shang being roughly in his mid-20s.
Ultimately, the specific ages of Mulan and Shang are not necessarily central to the story or its themes. What is more important is the journey that Mulan goes on to prove herself and become a hero, as well as the relationships and connections she forms along the way.
