What is Mulan's last name in the film?

Mulan’s last name in the 1998 animated film is Fa.

Her full name is Fa Mulan, and she is the daughter of Fa Zhou and Fa Li. The Fa family name appears throughout the film in names such as Grandmother Fa and the First Ancestor Fa, anchoring Mulan’s story in her family’s history and obligations.

When Mulan takes her father’s place in the army, she disguises herself as a man named Fa Ping. That alias preserves the family name while concealing her identity from the other soldiers. Her decision is motivated by her concern for Fa Zhou, a veteran who is ordered to serve despite his age and injuries.

Viewers may remember “Hua Mulan” from the traditional legend or the 2020 live-action film. The animated film uses “Fa,” a Cantonese-based romanization. The live-action version changes the family name to Hua, which is the Mandarin pinyin romanization of the same Chinese surname.
