What does this mean in my passport

I have renewed my Taiwan passport at a Taipei Economic and Cultural Office in Toronto and at the back it was stamped with the following: “持照人出國應經核准”

What does that mean for me if I was to go back to visit?

I also have the overseas chinese stamp in the front.

It means you have to go to the entry-exit bureau and get permission to leave, since you’re of draft age. It takes a couple of days. You may be able to get a “multiple” stamp. You may also be able to do it online (this is an old link and I’m in China so it’s blocked, therefore I can’t verify it): nas.immigration.gov.tw/nasf/ctl … pplication
