Transit Visa -

Hello. Sorry it’s being asked again but I can’t wrap my head around the three points. I did go to the Wikipedia link and that one Reddit post that’s been pinned.

If we are travelling based on below itinerary do we qualify for the transit visa ?

Canada -> vancouver (layover) -> Hong Kong (flying via air canada

From Hong Kong join some tours to China for four days (bus or train). I will be coming back to Hong Kong with the tour.

Then from Hong Kong -> Taipei (layover) -> Seoul

Last Seoul -> canada

Is the transit visa point - A -> B -> C where B is China ? So meaning my travel won’t work because my A and C are Hong Kong right ?

Sorry for the repeated ask. Thank you
