Hi, I am European citizen, planned to travel to Taiwan and from there to HongKong.

We planned to go to Taiwan for 10 days and our return trip to stay in HongKong for 2 or 3 days.
do we need visa?
Above I understand that we can stay without entry permit for 90 days, but I read from some site something that if we go to HongKong from taiwan need to get visa before going to Taiwan??
Or does that also mean if stay over 90 days?
