Which one of these 2 DP's do u think was the first one to have a job? Mulan of Tiana?

Afew years ago, I was on Tiana's DP Wikia page, and I read somewhere in her trivia section saying she was the first DP to have a job, but seconde if u counted Mulan's service in the Chinese army. I eventually talked to my mom about this, and SHE thinks Mulan was the first DP to have a job.I got to thinking and I'd like to know what u guys think about this. Do u think Tiana was the first DP to have a job? of do u think Mulan was?
