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