Which one of these 2 DP's do Du think was the first one to have a job? Mulan oder 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 Sekunde if Du 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 Du guys think about this. Do Du think Tiana was the first DP to have a job? oder do Du think Mulan was?
