Which one of these 2 DP's do you think was the first one to have a job? Mulan or 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 second if you 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 you guys think about this. Do you think Tiana was the first DP to have a job? Or do you think Mulan was?
