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