[Mulan] Why is Mulan the only person with an ancestral guardian?
gpt
Ancestral guardians usually work behind the scenes, invisible and undetectable, but still able to influence matters with their vast powers.  If the Great Stone Dragon had awoken like the ancestors had intended, then that's likely how it would have operated.  

Mushu is not nearly so powerful, so he had to take a more hands-on approach.  

Thus, it's perfect possible that other people had active ancestral guardians watching over them, it's just that these guardians were not visible.  After all, Shang and the other soldiers do get rather lucky at times.
