Help me plz! Q on retirement

Hello guys, I hope the new year is going well.

For those of us who are planning on retiring here, I was wondering, what happens to healthcare for permanent residents?

Do we get free heathcare or do we still need to pay payments each moth? What will be covered and what will not? I don’t have any kids that will be able to support me etc! I’m 12 years away yet, but, what to know what I need to do ie: planning. I do have a pension fund.

Also, is there anyone who is retring now in Taiwan?
